Abstract Purpose of this study is: Assessing the role of Diffusion weighted imaging with ADC mapping in the evaluation of uterine cervical cancer post therapy regarding tumor residual, recurrence or post treatment benign changes/ complications after tumor resection and/or chemotherapy/radiotherapy. Methods The study included 48 female underwent cervical cancer treatment, referred to Radio diagnosis Department of National Cancer Institute for post therapy assessment. Each patient included in the study was subjected to full history taking, reviewing medical sheet and MR examination including: Conventional MR examination and Diffusion Weighted imaging. Results The study showed that the use of quantitative DW imaging with ADC mapping provide added value in the detection of post-treatment malignant masses and differentiating it from post-treatment benign changes. Conclusion The current application of diffusion Weighted MRI as a routine with conventional MRI sequences increased the accuracy of detection of post therapy benign and malignant masses , Our results suggested also that the use of ADC can be helpful in differentiating post-treatment malignant masses from benign post-treatment changes.

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.

Background. Xanthogranulomatous cholecystitis (XGC) is often misdiagnosed as gallbladder cancer (GBC). We aimed to determine the preoperative characteristics that could potentially aid in an accurate diagnosis of XGC masquerading as GBC.Methods. An analysis of patients operated upon with a preoperative diagnosis of GBC between January 2008 and December 2012 was conducted to determine the clinical and radiological features which could assist in a preoperative diagnosis of XGC.Results. Out of 77 patients who underwent radical cholecystectomy, 16 were reported as XGC on final histopathology (Group A), while 60 were GBC (Group B). The incidences of abdominal pain, cholelithiasis, choledocholithiasis, and acute cholecystitis were significantly higher in Group A, while anorexia and weight loss were higher in Group B. On CT, diffuse gallbladder wall thickening, continuous mucosal line enhancement, and submucosal hypoattenuated nodules were significant findings in Group A. CT findings on retrospect revealed at least one of these findings in 68.7% of the cases.Conclusion. Differentiating XGC from GBC is difficult, and a definitive diagnosis still necessitates a histopathological examination. An accurate preoperative diagnosis requires an integrated review of clinical and characteristic radiological features, the presence of which may help avoid radical resection and avoidable morbidity in selected cases.
