Category: Midfoot/Forefoot Introduction/Purpose: To the best of our knowledge, there are no previous reports comparing the radiographic findings to CT findings for symptomatic naviculo-medial cuneiform (NC) coalition. The purpose of this study was to demonstrate and compare the features of symptomatic naviculo-medial cuneiform coalition between radiography and computed tomography (CT). Methods: We retrospectively reviewed the radiographic and CT findings of 25 symptomatic naviculo-medial cuneiform coalition cases in 18 patients. The existence of a large pit (depth >3 mm), irregular articular surface, joint space narrowing, dorsal bony spur, subchondral sclerosis, multiple subchondral bony cysts, and intra-articular loose bodies were evaluated on radiograph or CT. The size of the largest subchondral bony cyst was also measured using CT. Results: The proportion of large pit observed on radiograph (52.0%) was significantly different (P = .001) from that on CT (72.0%). Similarly, intra-articular loose bodies were observed more frequently on CT (P = .001). The mean size of the largest subchondral bony cyst on CT was 4.25 mm. Conclusion: While evaluating CT in patients with naviculo-medial cuneiform coalition, physicians should focus on detecting a large pit and intra-articular loose bodies since differences in these features were frequently observed between radiograph and CT, with these findings being more evident on CT. We believe that a large subchondral bony cyst could also be related to the symptoms of naviculo-medial cuneiform coalition.

Abstract Background Varus ankle osteoarthritis is classified using only weightbearing anteroposterior ankle radiographs; however, sagittal ankle alignment may also affect the position and extent of joint space obliteration. We hypothesized that the sagittal alignment of the ankle may also affect the position and extent of joint space obliteration visible on the coronal section; therefore, we identified the sites of joint space obliteration in patients with stage 3 varus ankle osteoarthritis for comparison with the sites observed on simulated weightbearing computed tomography and investigated the effects of anterior and posterior ankle subluxation. Methods Simulated weightbearing computed tomography scans of 83 ft with varus ankle osteoarthritis (26 stage 3a, 57 stage 3b) were performed to check for joint space obliteration in the ankle. Further classification as exhibiting either anterior, posterior, or no subluxation on weightbearing lateral radiographs was performed. Results Anterior, posterior, and no subluxation was seen in 5, 9, and 12 ankles among the 26 classified as stage 3a, respectively, and in 22, 12, and 23 ankles among the 57 classified as stage 3b, respectively. The mean tibial lateral surface angle on weightbearing lateral radiographs in stage 3a ankles was 75.6, 83.3, and 80.3 degrees in the anterior, posterior, and no subluxation groups, respectively; and 75.5, 86.6, and 82.7 degrees in stage 3b ankles (p < .05). In stage 3b ankles, widespread joint space obliteration was observed at the anterior distal articular surface of the tibia in all 22 ankles with anterior subluxation and at the posterior distal articular surface of the tibia in all 12 ankles with posterior subluxation. Conclusions Simulated weightbearing computed tomography revealed joint space obliteration at the anterior distal articular surface of the tibia in stage 3b ankles with anterior subluxation and at the posterior side in stage 3a and 3b ankles with posterior subluxation. In some patients with stage 3 varus ankle osteoarthritis, the obliteration of the joint space is difficult to evaluate accurately using only weightbearing anteroposterior radiographs; weightbearing lateral radiographs should also be performed.

Category: Bunion Introduction/Purpose: Total arthroplasty or arthrodesis is often used as a surgical procedure for severe case of hallux rigidus. However, because these procedures involve problems such as loss of joint function, age, and postoperative motion restriction, joint-preserving surgery is desirable for achieving a better quality of life. To resolve these problems, we have performed dorsiflexion osteotomy of the first metatarsal head since 2000, yielding favorable outcomes. We report about middle to long-term follow-up for our clinical results and radiographic findings. Methods: The study involved 31 feet of 30 patients (20 male,11 female) with Grade 2 (joint space narrowed to about 1/2 or less) or Grade 3 according to the Hattrup and Johnson classification. The mean age at surgery was 61.6 years (range: 53-77). Surgical techniques: We have used dorsal approach and conducted closed wedge osteotomy of the first metatarsal bone neck. Then, the bone head was flexed dorsally to form an articular surface and fixation. PWB was permitted 3 weeks after surgery. Mean postoperative follow-up period was 4 years and 2 months (range: 3-13 years). Clinical outcomes, range of motion (ROM), and radiographic findings were investigated. Results: Clinical outcomes were rated as excellent in 24 feet, good in 7, and fair/poor in none. All patients returned to normal daily life. Stiffness while walking was noted in 10 feet. As for ROM, most patients had a 1/2 to 2/3 of the normal range. No complications such as infection, nonunion, or transfer metatarsalgia were seen in any case. An X-ray film showed joint space narrowing in about half of all cases. None of the patients experienced pain relapse requiring arthrodesis again. Conclusion: The mechanism of pain relief is Dorsiflexion osteotomy is by bone shortening, make a decreasing joint pressure and regaining of normal articular to the dorsal side so that it faces the articular surface of the proximal phalanx. The postoperative restriction of ROM may be attributable to changes in the bone alignment and in the tension of soft tissue around the joint as compared to the healthy condition. None of the patients experienced pain relapse. Our procedure appears to be useful as joint- preserving surgery for severe cases with hallux rigidus.

Abstract Background This study evaluated the time course of computed tomography (CT) findings of patients with COVID-19 pneumonia who required mechanical ventilation and were treated with favipiravir and steroid therapy. Results Eleven patients with severe COVID-19 pneumonia were included. CT findings assessed at the three time points showed that all patients had ground-glass opacities (GGO) and consolidation and mixed pattern at intubation. Consolidation and mixed pattern disappeared in most of the patients whereas GGO persisted in all patients at 1-month follow-up. In addition to GGO, a subpleural line and bronchus distortion and bronchial dilatation were frequent findings. The degree of resolution of GGO varied depending on each patient. The GGO score correlated significantly with the time from symptoms onset to initiation of steroid therapy (ρ = 0.707, p = 0.015). Conclusions At 1-month follow-up after discharge, non-GGO lesions were absorbed almost completely, and GGO were a predominant CT manifestation. Starting steroid therapy earlier after onset of symptoms in severe COVID-19 pneumonia may reduce the extent of GGO at 1-month follow-up.

Background:Diagnosis of axial spondyloarthritis (SpA) is nowadays commonly made with the help of pelvic radiography or MRI. However, there is an important inter-observer variability for radiographs, and MRI is subject to possible false positives, and is not the best modality for studying structural lesions. Conversely, pelvic CT has an excellent specificity and appears to be more effective than radiography for the diagnosis of SpA [1]. However, CT findings in patients over 50 years of age have not been studied.Objectives:To describe sacroiliac (SI) joint CT characteristics in patients with ankylosing spondylitis (AS), aged 50 years or older.Methods:An observational, cross sectional study was performed using medical records from Besançon University Hospital’s rheumatology department, which were screened to identify patients with AS. A search was then carried out for patients over 50 years old in the hospital’s imaging archiving system to identify those who had benefited from a CT which included the SI joints in their entirety. Non-inclusion criteria were the existence of pelvic bone lesions and a history of pelvic radiotherapy. For each patient, CT was interpreted using a score previously used by Diekhoff et al. [2], dividing each SI joint into 12 regions, for each of which joint space narrowing (JSN), erosions, and sclerosis are assessed. For this study, we also observed the existence of intra-articular gas and diffuse idiopathic skeletal hyperostosis (DISH) lesions for each region. Quantitative variables are expressed as mean ± standard deviation, qualitative variables as numbers and percentages. Wilcoxon rank-sum test was used to determine factors associated with a higher CT score.Results:A total of 66 patients were included. Mean (SD) age was 65.10 ± 10.59 with a mean (SD) duration of disease of 22.87 ± 14.95 years. 60.29% were male, and 87.04 % were HLA-B27 positive. 40.30% had a bamboo spine. CT findings are described in Table 1. The vast majority of patients have a positive JSN score but significant erosions are found in only a minority of cases. This is partly explained by the fact that 55.9% of the patients had at least one complete bilateral ankylosis (and therefore no erosions) on one of the three slices studied. Bilateral anklylosis was associated with a longer duration of disease (p<0.001) and presence of bamboo spine (p<0.001). Also noteworthy is the low proportion of DISH compared to the general population in this age group, which is 15-25%.Factors associated with a higher total CT score were male sex (p=0.017), longer duration of disease (p<0.001), tobacco use (p=0.033), presence of bamboo spine (p=0.004), absence of DISH (p=0.045) and absence of intra-articular gas (p<0.001). The distribution of lesions appeared to be homogenous over all 24 regions studied (Figure 1).Conclusion:CT findings in AS patients over 50 years of age are mostly represented by changes in joint space, with bilateral ankylosis present in half of the patients. AS appears to be a protective factor for DISH.References:[1]Devauchelle-Pensec V, D’Agostino MA, Marion J, et al.

Abstract Purpose Intraabdominal hypertension (IAH) in acute pancreatitis (AP) may reduce tissue perfusion and impair organ function and has been shown to portend poor prognosis. We investigated the computed tomography (CT) findings in patients with AP with IAH. Methods This retrospective study comprised of consecutive patients with AP from June 2016 to June 2018 in whom intraabdominal pressure (IAP) was measured. The patients who underwent a contrast-enhanced CT within 7 days of IAP measurement were included. Using a cutoff of 12 mm Hg for IAP, the patients were divided into IAH and non-IAH groups. Measures of severity and clinical outcome were evaluated. CT parameters were compared between the groups. Results The IAH group comprised of 41 patients, while there were 20 patients in the non-IAH group. The IAH group was characterized by severe disease, increased incidence of organ failure, increased requirement for drainage and surgery, prolonged hospital and intensive care unit stay. The mortality was not significantly different between the two groups. On univariate analysis, the CT features that were found to be significantly different between the two groups were the presence of collection (p = 0.036), the maximum dimension of collection (p = 0.004), volume of collection (p = 0.019), biliary dilatation (p = 0.011), and the presence of moderate-to-severe pleural effusion (p = 0.009). On multivariate analysis, all these parameters except biliary dilatation were found to be statistically significant. Conclusion CT findings in patients with AP may suggest IAH. This can be used as an additional marker for severity of AP.

AbstractSecondary hyperparathyroidism (sHPT) as a result of chronic kidney disease (CKD) is a common health problem and has been reported to manifest at the sacroiliac joints (SIJ). The aim of this investigation was to systematically assess sacroiliac joint changes in asymptomatic sHPT as detected by high-resolution CT. Included in this IRB-approved retrospective case–control study were 56 patients with asymptomatic sHPT as well as 259 matched controls without SIJ disease. Demographic data were retrieved from electronic patient records. High-resolution computed tomography datasets of all patients were subjected to a structured scoring, including erosions, sclerosis, osteophytes, joint space alterations and intraarticular calcifications. Chi2 tests were used to compare frequencies of lesions. Erosions were significantly more prevalent in patients with sHPT, and were found mainly in the ventral (28.6% vs. 13.9%; p = 0.016) and middle (17.9% vs. 7.7%; p = 0.040) iliac portions of the SIJ. Partial ankylosis was rare in both cohorts (3.6% vs. 5.0%; p > 0.999); complete ankylosis was not observed. Neither extent not prevalence of sclerosis or calcifications differed significantly between groups. Joint lesions reminiscent of sacroiliitis can be found in a substantial portion of asymptomatic patients with secondary hyperparathyroidism. Further investigations into the clinical significance of these findings are warranted.

Fulminant invasive fungal rhinosinusitis is an aggressive, destructive process most commonly affecting the immunocompromised host. Although frequently fatal, prognosis is related directly to early recognition and aggressive treatment. Various reports advocate computed tomography (CT) scanning as the study of choice in evaluating suspected invasive fungal disease, reserving magnetic resonance imaging (MRI) for select cases. Others report lack of correlation between CT and surgical or pathological findings. Our aim was to investigate the usefulness of CT and MR in the diagnosis of invasive fungal rhinosinusitis. We retrospectively reviewed four cases of biopsyproven invasive disease. Correlations between radiographic, endoscopic, and surgical findings were investigated. Rhizopus species were detected in three cases and mixed Mucor and Aspergillus species in another. Superimposed bacterial sinusitis was confirmed in all cases. CT findings were nonspecific, revealing pansinusitis; no bone destruction or intracranial extension was noted. Mild orbital cellulitis was noted in one case. Anterior rhinoscopy revealed nonviable tissue in two patients. Nasal endoscopy later confirmed tissue ischemia in a third patient, whereas a final patient had normal findings on both exams. Nonspecific findings resulted in delay of diagnosis by 48–72 hours in two patients with presumed bacterial sinusitis. MR revealed intracranial extension in two patients and better represented intraoperative findings. In conclusion, CT findings in invasive fungal rhinosinusitis may be nonspecific and underestimate extent of disease. A high index of suspicion and early endoscopic examination with biopsy are mandatory for evaluation. MRI may better represent disease progression and should be considered early.

Introduction: In human body there are many causes of the injuries. Among all the injuries head injury is also one of the most important injuries which may cause morbidity and mortality. Craniocerebral injuries or Traumatic brain injury (TBI) is defined as any structural skull traumatic injury with alterations of cerebral physiology as a result of an external force either in the form of chemical energy, mechanical energy, electrical energy or thermal heating. Globally craniocerebral injuries or Traumatic brain injury (TBI)is cause of disability in young patients, especially those  <40 years of age. TBI is classified as mild, with most showing adequate and quick recovery. Nevertheless there are some kinds of TBI which showed persistent disabling symptoms that interrupt with their normal daily routine activities. Brain imaging is very important for the patients who suffer traumatic brain injury. In the emergency services Computed tomography (CT) is recommended as first assessment that provides initial information and diagnosis to identify the need of surgery. It also helps in the following of the patient and the evolution of pathology. Many studies suggest that CT can be used to predict patient outcomes. Computed tomography (CT) is an imaging technique which uses as dynamics of injected contrast material, allows rapid quantitative and qualitative evaluation of cerebral perfusion by generating cerebral blood volume (CBV), cerebral blood flow (CBF) and mean transit time (MTT) maps providing clinically important information with stroke subarachnoid hemorrhage (SAH)and head injury. Aim: The main aim of this study is to evaluate the computed tomography findings sustaining head injury and role of computed tomography scan in head injury. Material and Methods: During the study total 90 patients with head injury were included with different age group from 20 to 70 years old. Glasgow coma score (GCS) range 4–15 (mild head injury: GCS >14; moderate head injury: GCS = 9–13; severe head injury GCS <8) were also included in this study. For all the patients with head injury Computed tomography (CT) image were performed with siemen's somatom spirit dual slice spiral CT machine and a protocol of contiguous axial 5-mm sections through the posterior fossa and a contiguous 10 mm axial sequential scans for the rest of the brain and thinner cuts were also taken whenever required. For visualize any fractures of the skull bone algorithms with wide window settings were studied. After initial resuscitation, severity of the cranio-cerebral trauma was graded with the help of Glasgow Coma Scale (GCS) into mild head injury (GCS13- 15), moderate head injury (GCS 9-12) and severe head injury (GCS 3-8). Result: Among total patients sixty five (72.2%) patients were male and twenty five (27.8 %) were female with age range from 20 to 70 years old. In the age group 31-50 year group showed highest frequency of head trauma. The most common causes of head injury were RTA (65.6%) followed by fall injuries (20%) and physical assaults (14.4%). Among patients with head injuries Loss of consciousness and vomiting were the commonest clinical features brought to emergency. Out of 90 cases 59 (65.5%) cases showed mild head injury followed by 14(15.6%) cases sustained moderate head injury and 17(18.9%) had severe head injury. In all types of severity of head injury RTA was the prime etiological factor. Out of total cases 31(34.4%) had normal CT findings and 59(65.6%) had abnormal CT findings. Abnormal CT findings were seen in 59(65.6%) sustaining mild head injury and in all the patients with moderate and severe head injury. Out of 90 cases 13 cases with severe head injury had mortality. The most common mode of injury to cause the mortality was RTA. Five patients with severe head injury also had cervical spine injury Conclusion: This study concludes that use of CT in head trauma can finds high prevalence of head trauma related to CT. Therefore CT should be done when clinically necessary that helps to reduce cost and avoids unnecessary exposure to radiation. Keywords: Head injury, Traumatic brain injury (TBI), computed tomography (CT), Glasgow coma scale (GCS)

Background: Abdominal injury constitutes a significant portion of all blunt and penetrating body injuries. Computed   tomography is an important and fast technique which gives rapid information on the type of abdominal injury and helps in management of the patient accordingly. The aim of the present study was to evaluate the usefulness of Multidetector Computed Tomography (MDCT) in detection of intra-abdominal injury in patients with blunt abdominal trauma and to provide information that could accurately determine choice of management (non- operative versus operative). And to correlate the computed tomography (CT) findings with either clinical observation, follow up CT scan (if required) or surgical findings (wherever applicable).Methods: A total of 50 patients with abdominal trauma who underwent computed tomography (CT) examination were included. CT findings were compared with surgical findings in operated cases, and in the rest CT findings were compared by clinical outcome.Results: Among the 50 cases studied, all 50 had positive CT findings of abdominal trauma, out of which 24 patients underwent surgery and the remaining were managed conservatively. The age group of the patients was ranging from 8 to 66 years with male predominance. In this study the commonest organs affected were liver and spleen accounting for 48% and 44% respectively.Conclusions: Computed tomography is an important and highly sensitive imaging modality for diagnosis of organ injuries in patients with abdominal trauma and accordingly deciding the management of patient.
