Case 127:   Metastasis - Neuroendocrine Tumor

Diagnostic Category:

Clinical Presentation:

44 year old man with metastatic carcinoid tumor of the distal ileum.

CT: Carcinoid in hepatic steatosis

Imaging Findings:

CT shows hypervascular metastases, within a fatty liver. Note that the masses are hyperdense to background liver parenchyma on the unenhanced images. The masses demonstrate hyperdensity on equilibrium phase, which visually does not allow the distinction between subtle washout and prolonged enhancement in a fatty liver. However, washout is appreciated when attenuation coefficient is quantified.
