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.

<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.

SUMMARY OBJECTIVE: To determine the computed tomography (CT) signs associated with stercoral perforation and colorectal cancer perforation. MATERIALS AND METHODS: From May 2003 to Feb. 2015, all surgically and pathologically confirmed patients with stercoral perforation (n=8, mean age 68.3 years) or colon cancer perforation (n=11, mean age 66.3 years) were retrospectively reviewed by two board-certified radiologists blinded to the proven diagnosis. The following CT findings were evaluated and recorded for each patient: wall thickness of the distal colon adjacent to perforation site, pattern of the colon wall thickening and enhancement, length of the thickened bowel wall, presence of fecaloma, degree of proximal colon dilatation, and pericolonic inflammation or presence of pericolonic abscess, and number of enlarged pericolonic lymph nodes. These findings were correlated with the pathologic diagnosis. RESULTS: The mean thickness of the distal colonic wall adjacent to the perforation site was 13.6 mm in patients with colorectal cancer perforation and 5.1 mm with stercoral perforation, which was statistically different. There was a significant correlation between colorectal cancer perforation and eccentric wall thickening (p<0.01). CT findings of layered enhancing wall thickening (p<0.01) and the presence of fecaloma in the proximal colon (p<0.01) were significant findings for stercoral perforation. Patients with colorectal cancer displayed more pericolonic lymph nodes (mean 2.27, p<0.05). CONCLUSION: Fecaloma in the proximal colon and layered enhancing wall thickening adjacent to perforation site are likely due to stercoral perforation. Eccentric bowel wall thickening at the distal portion of the perforation site with many enlarged pericolonic lymph nodes is most likely due to colorectal cancer perforation.

Abstract Background Although several cases with pneumoperitoneum that does not require surgical intervention (nonsurgical pneumoperitoneum) have been reported, the characteristics of such cases remain unclear. The accurate diagnosis of nonsurgical pneumoperitoneum could minimize unnecessary surgery. The aim of this study was to clarify the clinical and radiological characteristics of cases with nonsurgical pneumoperitoneum detected using computed tomography. Methods This retrospective study was conducted at a single center. A total of 18513 abdominal computed tomography (CT) scans obtained between January 2010 and February 2017 were examined for pneumoperitoneum. Medical records of cases testing positive for extraluminal free air were analyzed. Results Extraluminal free air was detected in 254 examinations of 182 cases. Out of 88 examinations of 86 cases excluding iatrogenic air, colorectal perforation was the most common cause of extraluminal free air. Nonsurgical pneumoperitoneum was recognized in 25 examinations of 23 cases, and was the second most frequent. The frequency of nonsurgical pneumoperitoneum was 0.14% in all abdominal CT examinations. Most nonsurgical pneumoperitoneum cases did not exhibit severe general conditions, peritoneal signs, or leukocytosis. CT findings of bowel wall discontinuity, segmental bowel-wall thickening, perivisceral fat stranding, and abscess were not observed. Fluid collection was present in 8 of 23 cases, and the estimated volume of fluid collection was small. Pneumatosis intestinalis was simultaneously observed in 20 of 23 cases. No significant differences in the maximum diameter of intraperitoneal free air were observed between the grades of pneumatosis intestinalis (p=0.999). Follow-up CT examination, which was performed within 7 days after the detection of nonsurgical pneumoperitoneum, showed that the pneumatosis intestinalis and/or extraluminal free air often disappeared in a short time. Conclusions Nonsurgical pneumoperitoneum was common. The cause of extraluminal free air was pneumatosis intestinalis in most cases. Well-maintained general and local conditions and normal laboratory data were the clinical characteristics. The absence of CT findings indicative of peritonitis, little fluid collection, if any, and the presence of pneumatosis intestinalis were the radiological characteristics.

Abstract Background Although gall bladder perforation (GBP) is not common, it is considered a life-threating condition, and the possibility of occurrence in cases of acute cholecystitis must be considered. The aim of this study was to assess the role of multi-slice computed tomography (MSCT) in the assessment of GBP. Results It is a retrospective study including 19 patients that had GBP out of 147, there were 11 females (57.8%) and 8 males (42.1%), aged 42 to 79 year (mean age 60) presented with acute abdomen or acute cholecystitis. All patients were examined with abdominal ultrasonography and contrast-enhanced abdominal MSCT after written informed consent was obtained from the patients. This study was between January and December 2018. Patients with contraindications to contrast-enhanced computed tomography (CT) (pregnancy, acute kidney failure, or allergy to iodinated contrast agents) who underwent US only were excluded. Patients with other diagnoses, such as acute diverticulitis of the right-sided colon or acute appendicitis, were excluded. The radiological findings were evaluated such as GB distention; stones; wall thickening, enhancement, and defect; pericholecystic free fluid or collection; enhancement of liver parenchyma; and air in the wall or lumen. All CT findings are compared with the surgical results. Our results revealed that the most important and diagnostic MSCT finding in GBP is a mural defect. Nineteen patients were proved surgically to have GBP. Conclusion GBP is a rare but very serious condition and should be diagnosed and treated as soon as possible to decrease morbidity and mortality. The most accurate diagnostic tool is the CT, MSCT findings most specific and sensitive for the detection of GBP and its complications.

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.
