Case 303:   Cholangiocarcinoma

Diagnostic Category:

Clinical Presentation:

56 year old man with abdominal pain.

CT: non-specific hypodense focus

Imaging Findings:

Unenhanced CT show steatosis with irregular focus of hypodensity in segment 2. This finding is not specific, but was not investigated further and turned out biopsy proven cholangiocarcinoma 1.5 years later.

Hypodense irregular lesions like this example could represent focal fatty infiltration or hypodense sparing, but further investigation should be recommended upon detection of findings like this.
