RADIOLOGY: HEPATOBILIARY: Case# 33558: PORCELIN GALLBLADDER. 55 year old female with known metastatic melanoma who is currently receiving chemotherapy. 1. Hepatic and splenic metastases are again seen. No definite new metastases are seen. The size of these metastases is either unchanged or possibly slightly larger - owing to intraobserver measurement differences. 2. Thickened, calcified gallbladder wall, gallbladder contains central heterogeeous density material, possibly sludge or stones but is worrisome for metastatic disease. 3. Solitary 1 cm omental node, inflammatory vs neoplastic; comparision with the prior outside CT would be helpful in assessing for interval change.
