The gallbladder is grossly abnormal. Is this benign or malignant pathology?
Although it can be challenging to distinguish benign and malignant gallbladder pathology on imaging, and they may coincide, here the imaging features are typical of xanthogranulomatous cholecystitis with dilated hypo-enhancing spaces in the wall and an intact mucosa.
- The gallbladder wall is grossly thickened and has large low attenuation spaces within the wall which do not communicating with the gallbladder lumen.
- Calculus impacted in the gallbladder neck causing distension of the gallbladder lumen.
- Chronic pancreatitis with parenchyma and ductal stones and pancreatic ductal dilatation.
- Large pseudocyst in the pancreatic head.
