Case 142: Peliosis Hepatis

Diagnostic Category:

Clinical Presentation:

45 year old asymptomatic woman.

CT: Centrifugal ring enhancement

Imaging Findings:

Multiphase CT of peliosis reveals a mass that enhances centrally in the arterial and portal venous phases. In the equilibrium phase, the previously non-enhancing periphery of the lesion now demonstrates ring enhancement, while the center is isodense to the remainder of the hepatic parenchyma. Several other smaller, similar appearing lesions were also present (not shown). Biopsy confirmed peliosis.
