title: Xanthogranulomatous cholecystitis: sonographic and CT features and differentiation from gallbladder carcinoma: a pictorial essay.
abstract: The imaging features of xanthogranulomatous cholecystitis closely resemble those of gallbladder carcinoma, especially those of the wall-thickening variety. There is an overlap between these two conditions with respect to the clinical features and certain imaging findings. However, certain finer details like the presence of intramural hypoattenuating nodules and the type of mucosal enhancement may help to differentiate these two conditions. In this article, we have highlighted some of these imaging features. The importance of making an accurate diagnosis lies in the significant difference between the prognosis and the surgical management of the two disease entities.
