MR findings in peliosis hepatis

Peliosis is an uncommon condition characterized by multiple-blood-filled cavities mostly involving the liver. Although the etiology is unknown the condition may be associated with several disease states and medications. We report the MR findings of peliosis hepatis in a patient with Fanconi anemia who had been treated with anabolic androgenic steroids for 3 years. The MR examination of the upper abdomen was performed on a 0.5 T system. The signal intensity of the right lobe of the liver was diffusely increased in all sequences. Within the enlarged liver, multiple foci of brighter signal were seen involving both right and left lobes. The lesions showed contrast enhancement. A cystic cavity with an enhancing rim was seen representing a haematoma cavity. The spleen was spared the patient died of sepsis and the postmortem examination confirmed the diagnosis of peliosis hepatis.
