Case 255: Cholangiocarcinoma
57 year old man with abdominal pain.
CT: Nodular type, with hypervascularity and fibrotic enhancement, in steatosis
Multiphase CT shows steatotic liver parenchyma with biopsy proven moderately differentiated cholangiocarcinoma in segment 2/4a. Typical arterial hypervascularity and subtle central fibrotic progressive enhancement of the mass.
Presence of tumor was indirectly suggested by subtle finding on CT 1.5 years earlier.
