title: Hepatitis C-related primary effusion lymphoma of the pleura and peritoneum, imaged with F-18 FDG PET/CT.
abstract: Primary Effusion Lymphoma (PEL) is a rare form of Non-Hodgkin lymphoma that involves serous body cavities (pleural, pericardial, or peritoneal) with lymphomatous effusions in the absence of lymphadenopathy or organomegaly. Although it was seen mostly in HIV-positive patients, it has recently been reported in HIV-negative patients with chronic Hepatitis B or C infections. PEL is associated with human herpes virus type-8 infection, often presents with rapidly progressive effusions and generally has a poor prognosis. This is a case of a 65-year-old HIV-negative man with Hepatitis C cirrhosis, who presented with abdominal pain. An F-18 FDG PET/CT showed marked ascites and pleural effusions with increased F-18 FDG uptake in the pleura and peritoneum on the left side. Analysis of the cells in the peritoneal fluid revealed a human herpes virus 8-positive PEL of the peritoneum. As a result the patient was no longer considered a liver transplant candidate and died 2 weeks after the diagnosis.
