ABSTRACT Objective To correlate magnetic resonance imaging (MRI) findings with the microbiological and anatomopathological diagnosis of spinal infection. Methods A retrospective, cohort review of online medical records (laboratory, anatomopathology and diagnostic imaging sector) of patients diagnosed with spondylodiscitis, who underwent a full spine MR scan between January 2014 and July 2018 at the Department of Orthopedics and Traumatology of the Universidade Federal de São Paulo. Results Staphylococcus aureus was the most commonly found etiological agent (57%). Blood culture was positive in 76% of cases and 82% of the patients who underwent biopsy had a spondylodiscitis diagnosis. Pain was the most prevalent clinical symptom and the lumbosacral spine was the most frequent site of infection. T1 hyposignal, T2/STIR hypersignal, and terminal plate destruction were verified in almost all MR scans. Conclusions No direct correlation was found between MR findings and any specific etiological agent. Blood culture and biopsy are important diagnostic tools that should be used for accurate diagnosis of the infectious agent . Level of evidence IV; Diagnostic Study.

ABSTRACT Cholestasis jaundice results from diminished bile flow and/or excretion, and caused by a number of disorders such as biliary atresia (BA). Magnetic resonance cholangiopancreatography (MRCP) is widely accepted as one of the modalities for biliary system imaging; however, liver biopsy still generally used for BA diagnosis, especially in developing countries. This aim study was to evaluate the diagnostic value of biliary atresia from MRCP compared to the result of a liver biopsy. A cross-sectional for diagnostic study documented of hospitalized patients from June 2014 to June 2015. All patients had MRCP and liver biopsy examination. The collection of data including age, gender, clinical manifestation and the result of MRCP and liver biopsy with ROC to evaluate the sensitivity and specificity was done. Liver biopsy revealed of biliary atresia was made based on proliferation, degeneration, and fibrosis of bile ducts. ROC to evaluate the sensitivity and specificity was done. The sensitivity, specificity, negative predictive value, positive predictive value of MRCP in diagnosing BA were calculated. There were 16 patients enrolled in this study with a median age of diagnosis was 6 months old (range 3-11). There were nine female patients out of the 16 patient. The median age of jaundice onset was 5 days (range 2-14 days). All patients had hepatomegaly and splenomegaly. Histopathology from liver biopsy revealed biliary atresia in 12 patients. From the ROC curve, the sensitivity of MRCP was 87.5% and specificity 62.5% with PPV 70% and NPV 80%. Five patients underwent a Kasai procedure and revealed biliary atresia. MRCP is sensitive but not specific for diagnosing BA, and MRCP has moderate sensitivity and specificity for BA diagnosis.Keyword: biliary atresia, magnetic resonance cholangiopancreatography, liver biopsy, diagnostic test.Correspondence: [email protected] ABSTRAKIkterus dikarenakan kolestasis terjadi akibat berkurangnya aliran empedu dan/ atau ekskresi, dan dapat disebabkan oleh sejumlah gangguan seperti atresia biliaris (BA).

Reformatted magnetic resonance imaging scans of 27 normal wrists were examined in incremental degrees of rotation around the central axis of the radial shaft to 30° in both directions from true lateral. A line was superimposed on the outer border of the radial dorsal cortex and continued distally to the carpal region. Measurements were made from the superior pole of the lunate to this line. This distance did not change significantly with rotation. This allows a quick and accurate way of assessing distal radial fracture reduction from poorly taken lateral radiographs. In addition, the relevant landmarks are not obscured by implants or casts. Level of evidence: III, diagnostic study

<p>There are contradictory reports on the findings of magnetic resonance image (MRI) in lumbar intervertebral disc prolapse. A study was conducted on 54 patients using 3 of 4 clinical criteria (low back pain with radiation down to the lower limbs, radicular pain along specific dermatomes, positive straight leg raising test, presence of neurological symptoms and signs e.g. motor or sensory deficit and MRI of lumbosacral spine of the respondent). Evaluation of MRI of lumbosacral spine was done based on extent of disc prolapse, disc degeneration, nerve root compression neural foramen compromise. The logistic regression analysis between the findings of MRI and the clinical features show that there was a significant association in the neural foramen or lateral recess (Odd's ratio 7.106, p&lt;0.05), the root compression (p&lt;0.01) as well as the disc extrusion (p&lt;0.05). There was no statistical association between clinical levels and other MRI findings like disc protrusion and disc bulge (p value 0.21 and 0.14, respectively). The strength of agreement between clinical and MRI diagnosis level of disc prolapse was calculated using kappa statistics (k-value). The test revealed a very good agreement for L3/4 (k-value = 0.812) and good agreement for L4/5 and L5/SI  level (k-value 0.75 and 0.75 respectively) between these two procedures, suggesting that level of disc prolapse could be correctly  diagnosed without MRI findings.  In conclusion, clinically diagnosed levels associate well with MRI levels, but all MRI abnormalities do not have any clinical significance.</p><p> </p>

Background The clinical relevance of medial patellofemoral ligament (MPFL) injury location in primary patellar dislocation has not been studied. Hypothesis Prognosis after primary traumatic patellar dislocation may vary by MPFL injury location. Study Design Cohort study; Level of evidence, 3. Methods The initial magnetic resonance imaging (MRI) findings in 53 patients with identical nonoperative management were retrospectively analyzed for medial restraint injuries. The MPFL injury sites were classified as follows: femoral, midsubstance, and patellar. Magnetic resonance imaging was used to assess initial and control articular cartilage lesions in the patellofemoral joint. After a mean follow-up of 7 years, 42 patients were evaluated for redislocations, subjective symptoms, and functional limitations. Results Based on the initial MRIs, MPFL rupture was classified as femoral in 35 patients, midsubstance in 11, and patellar in 7. At follow-up, 15 patients reported an unstable patella (13 femoral, 1 patellar, 1 midsubstance; P =. 01) and 9 reported patellar redislocations (8 femoral, 1 midsubstance; P =. 05). The proportion of patients who regained their preinjury activity level was significantly smaller among those with femoral MPFL injury than among those with midsubstance or patellar MPFL injury (P =. 05). The median Kujala score was as follows: 90 for femoral, 91 for patellar, and 96 for midsubstance (P =. 76). Control MRI showed full-thickness patellofemoral cartilage lesions in 50% of the patients, unrelated to MPFL injury location. Conclusion An MPFL avulsion at the femoral attachment in primary traumatic patellar dislocations predicts subsequent patellar instability. The authors suggest that MPFL injury location be taken into account when planning treatment of primary traumatic patellar dislocation.

Background: Magnetic resonance imaging (MRI) and ultrasonography are used widely for the diagnosis of Morton’s neuroma. The aim of this study was to assess the accuracy of these two modalities as diagnostic tools in Morton’s neuroma. Methods: Fifty feet of 47 consecutive patients (39 women and 8 men; mean age, 46 years; age range, 36–64 years) who presented between January 1, 2005, and June 30, 2008, were included in the study. Twenty-five feet were investigated with ultrasonography and 25 with MRI. Morton’s neuroma was confirmed surgically and histologically in all of the patients. A Student unpaired t test was applied. Results: Twenty-two MRIs were diagnostic (sensitivity, 88%). Three patients with negative MRI findings underwent ultrasonography and were found to have a neuroma smaller than 5 mm. Twenty-four ultrasound scans demonstrated the neuroma (sensitivity, 96%), with five neuromas being smaller than 5 mm. Conclusions: Ultrasonography has a slightly higher sensitivity in the diagnosis of Morton’s neuroma, particularly of neuromas smaller than 5 mm, and should be the preferred imaging modality in suspected cases, and MRI should be reserved for cases with equivocal diagnosis.

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.

Background Obtaining wrist radiographs prior to surgeon evaluation may be wasteful for patients ultimately diagnosed with de Quervain tendinopathy (DQT). Questions/Purpose Our primary question was whether radiographs directly influence treatment of patients presenting with DQT. A secondary question was whether radiographs influence the frequency of injection and surgical release between cohorts with and without radiographs evaluated within the same practice. Patients and Methods Patients diagnosed with DQT by fellowship-trained hand surgeons at an urban academic medical center were identified retrospectively. Basic demographics and radiographic findings were tabulated. Clinical records were studied to determine whether radiographic findings corroborated history or physical examination findings, and whether management was directly influenced by radiographic findings. Frequencies of treatment with injection and surgery were separately tabulated and compared between cohorts with and without radiographs. Results We included 181 patients (189 wrists), with no differences in demographics between the 58% (110 wrists) with and 42% (79 wrists) without radiographs. Fifty (45%) of imaged wrists demonstrated one or more abnormalities; however, even for the 13 (12%) with corroborating history and physical examination findings, wrist radiography did not directly influence a change in management for any patient in this series. No difference was observed in rates of injection or surgical release either upon initial presentation, or at most recent documented follow-up, between those with and without radiographs. No differences in frequency, types, or total number of additional simultaneous surgical procedures were observed for those treated surgically. Conclusion Wrist radiography does not influence management of patients presenting DQT. Level of Evidence This is a level III, diagnostic study.

Balo’s concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as “onion bulb.” We present a case of BCS and discuss the imaging findings and management strategies of this disease. A 26-y-old male developed headache, weakness, and numbness of limbs. Magnetic resonance imaging (MRI) showed concentric lamellar like demyelinating lesions at the subcortical regions. The patient’s neurological symptoms were consistent with the MRI findings.

Background: Rotational ankle instability (RAI) is associated with the faster onset of severe ankle osteoarthritis via dysfunction of the anterior talofibular ligament, calcaneofibular ligament, and deltoid ligament. No specific clinical examination is available for RAI, and diagnostic imaging has limitations in evaluating ligament degradation. This study investigated the deltoid ligament degeneration using Hounsfield unit (HU) values on computed tomography (CT) images. Methods: Patients were enrolled in this retrospective analysis if they had undergone magnetic resonance imaging (MRI) and CT scans of the ankle. The chronic ankle instability (CAI) group comprised 20 ankles with CAI (9 men, 11 women; mean age, 28.7 years) and the control group comprised 28 ankles (16 men, 12 women, mean age, 41.3 years). The average HU values of the deep posterior tibiotalar ligament (dPTL) that constitutes the deltoid ligament were measured on coronal CT images, and MRI results were used as a reference. All patients were subdivided based on the MRI findings of dPTL injury such as fascicular disruption, irregularity, and the loss of striation. Results: A strong negative correlation was identified between age and HU values for all patients (Spearman ρ = −0.63; P < .001). The mean HU values of the dPTL for participants aged <60 years were 81.0 HU for the control group (21 ankles) and 69.5 HU for the CAI group ( P = .0075). No significant differences in the HU values were observed for the dPTL among the MRI subgroups. Conclusion: In addition to the conventional imaging examination such as stress radiographs and MRI, HU measurements of CT images could be useful for quantitatively and noninvasively evaluating degenerative changes in the deltoid ligament for CAI patients to assist the diagnosis of RAI. Level of Evidence: Level III. case-control study.
