<b><i>Introduction:</i></b> Management of patients with atypical urinary cytology (class III) of the upper urinary tract is often complicated because some patients develop upper urinary tract urothelial carcinoma (UTUC). Here, we aimed to help define the optimal management of these patients. <b><i>Methods:</i></b> We investigated 31 patients who underwent retrograde ureteropyelography (RP) and were diagnosed with atypical findings of upper urinary tract cytology. <b><i>Results:</i></b> UTUC was revealed in 17 of 31 patients during the follow-up period of 1 year or longer. Tumor-like lesions and wall thickening in the upper urinary tract on initial computed tomography (CT) were significant predictors of UTUC (<i>p</i> = 0.0002 and <i>p</i> = 0.012, respectively). All 11 patients with tumor-like lesions and 3 of 8 patients with wall thickening on initial CT underwent nephroureterectomy, and UTUC was confirmed histologically. Moreover, 3 of 12 patients with hydronephrosis only or with normal findings later went on to develop UTUC. Repeated RP performed within 6 months from the initial RP was able to distinguish patients with UTUC from those without, even in individuals with normal CT findings. <b><i>Discussion/Conclusion:</i></b> Repeated RP based on initial CT findings is recommended in patients with atypical urinary cytology of the upper urinary tract. Nephroureterectomy without repeated RP may be warranted in patients with tumor-like lesions on initial CT findings.

Among patients with bronchiectasis, nontuberculous mycobacterial pulmonary disease (NTM-PD) ranged between 1 and 6% and it is suspected that its prevalence is underestimated. Our aim was to evaluate differences in computed tomography (CT) features in patients with bronchiectasis, with and without NTM-PD, in order to facilitate earlier diagnosis in the future. In addition, we evaluated longitudinal changes after successful NTM-PD treatment. One hundred and twenty-eight CTs performed in adults with bronchiectasis were scored for the involvement, type, and lobar distribution of bronchiectasis, bronchial dilatation, and bronchial wall thickening according to Reiff. In addition, associated findings, such as mucus plugging, tree-in-bud, consolidations, ground-glass opacities, interlobular thickening, intralobular lines, cavities, and atelectasis, were registered. Patients with NTM-PD (n = 36), as defined by ATS/IDSA diagnostic criteria, were compared to bronchiectasis patients without NTM-PD (n = 92). In twelve patients with an available consecutive CT scan after microbiological cure of NTM-PD imaging findings were also scored according to Kim and compared in the course. In patients with NTM-PD, there was a higher prevalence of bronchiectasis in the middle lobes (p < 0.001), extended bronchiolitis (p = 0.032) and more small and large nodules (p < 0.001). Furthermore, cavities turned out to be larger (p = 0.038), and walls thickened (p = 0.019) and extended (p = 0.016). Patients without NTM more often showed peripheral ground-glass opacities (0.003) and interstitial changes (p = 0.001). CT findings decreased after successful NTM-PD treatment in the follow-up CT; however, without statistical significance for most features (p = 0.056), but bronchiolitis was the only significantly reduced score item (p = 0.043). CT patterns in patients with bronchiectasis and NTM-PD differ from those of patients with bronchiectasis without NTM-PD, although the findings are non-specific radiological features. Follow-up CT findings after microbiological cure differed interindividual regarding the decline in imaging features. Our findings may help practitioners to identify NTM-PD in patients with bronchiectasis. Further research is needed regarding the use of CT as a potential imaging biomarker for the evaluation of treatment response.

Transitional cell carcinoma of the upper urinary tract is rare and presents quite interesting diagnostic and therapeutic problems. Available case studies, in accordance with literature on the subject, show how diagnosis relies on the combination of several data obtained from both traditional radiological methods and complementary tests. The importance of urography and retrograde ureteropyelography in providing morphological information is therefore fundamental and should be emphasised. It is advisable, however, to combine these data with those from urinary cytology, ultrasonography and to a lesser extent from CT scan, to be more sure of the nature and the extent of the disease.

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.

The present study aimed to review high resolution computed tomography findings in patients with H1N1 influenza A infection. The most common tomographic findings include ground-glass opacities, areas of consolidation or a combination of both patterns. Some patients may also present bronchial wall thickening, airspace nodules, crazy-paving pattern, perilobular opacity, air trapping and findings related to organizing pneumonia. These abnormalities are frequently bilateral, with subpleural distribution. Despite their nonspecificity, it is important to recognize the main tomographic findings in patients affected by H1N1 virus in order to include this possibility in the differential diagnosis, characterize complications and contribute in the follow-up, particularly in cases of severe disease.

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.

BackgroundMost patients with multiple sclerosis (MS) develop multiple urological complaints due to hyperactive or hypoactive bladder, and may have detrusor-sphincter dyssynergia. Routine renal ultrasound (RUS) screening has been recommended for both symptomatic and asymptomatic MS patients; however, there is little data to support this practice.MethodsProspectively screened consecutive MS clinic patients in 2016–2017 with functional systems scores (FSS) indicating moderate to severe neurogenic bladder symptoms (FSS bladder ≥2) were sent for RUS. We also screened for history of urinary tract infections.Results872 patients were screened between 3 September 2016 and 13 April 2017. 58 patients met inclusion criteria for RUS. 6 were excluded due to non-compliance with testing or unavailability of results; 52 patients were imaged. Only 3/52 patients were found to have renal pathology requiring follow-up. Of those three, one had known symptomatic nephrolithiasis, and one had subsequently normal findings, leaving one patient newly found to have valid abnormal upper urinary tract (UUT) findings. Multiple incidental findings were also discovered.ConclusionThe minimal yield for significant UUT pathology found in this enriched group of symptomatic MS patients indicates that RUS screening for asymptomatic MS patients without clear risk factors is not indicated. Red flags for high risk of UUT complications should be used as triggers for baseline RUS screening in MS patients.

Background Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis. The differential diagnoses of XGC include gallbladder cancer (GBC), adenomyomatosis, and actinomycosis of the gallbladder. Purpose To assess the usefulness of computed tomography (CT) findings in the diagnosis of XGC and differentiation from GBC. Material and Methods We retrospectively assessed the pathological and radiological records of 13 patients with pathologically proven XGC and 33 patients with GBC. Results Significant differences were observed for the following five CT findings: diffuse wall thickening (XGC = 85%, GBC = 15%, P < 0.01); absence of polypoid lesions (XGC = 100%, GBC = 48%, P < 0.01); intramural nodules or bands (XGC = 54%, GBC = 9%, P < 0.01); pericholecystic infiltration (XGC = 69%, GBC = 9%, P < 0.01); and pericholecystic abscess (XGC = 23%, GBC = 0%, P = 0.018). We defined the scoring system based on how many of the five CT findings were observed. Our scoring system, which included these findings, revealed that patients with three or more findings had sensitivity of 77% (95% confidence interval [CI] = 57–87) and specificity of 94% (95% CI = 86–98). Conclusion Our scoring system can assist in the differentiation of XGC from GBC.
