Case 25: Cholangiocarcinoma
71 year old woman presents with abdominal pain.
CT: Typical peripheral fibrotic enhancement
Multiphase CT reveals a large central hepatic, biopsy proven cholangiocarcinoma and multiple metastases. Note typical central necrosis and delayed enhancement of the masses, representing desmoplastic stroma reaction. However more commonly seen with cholangiocarcinoma is the reversed pattern of peripheral washout and fibrotic enhancement centrally.
