- To review a wide spectrum of pathologies that can involve the gallbladder wall - To utilize a pattern recognition approach in the differential diagnosis of these conditions. - To correlate the salient imaging features of these pathologies with histopathological findings.  

.- Introduction. - Technical background. - Patterns of gallbladder wall involvement:: - Diffuse wall thickening. - Focal/non-uniform wall thickening. - Polyp; benign and malignant. - Wall perforation/fistula. - Infiltrative processes. - Pathognomonic signs in the gallbladder wall: - Calcification. - Gas. - Cysts. - Intramural nodules/abscesses. -Hemorrhage. -Sloughed membranes. - Differential Diagnoses. - Summary and conclusion.  

A wide spectrum of neoplastic and non-neoplastic conditions involves the gallbladder wall. Because of morphologic overlap at imaging, accurate characterization of these lesions can be difficult. Pattern recognition has been proposed that is based on the morphologic features of the gallbladder wall and presence of certain pathognomonic features within. This approach can be helpful in characterizing these pathologies, narrowing the differential diagnosis, and guiding management of these conditions
