Abstract

A 46-year-old man with liver lesions referred to us as having "metastases of a malignant mesenchymal tumor" underwent PET/computerized tomography (CT) imaging for the localization of the primary tumor and determination of the extent of disease. No pathological FDG uptake was observed in PET/CT images obtained after 60 min, following FDG injection but delayed PET/CT images demonstrated intense FDG uptake at the liver masses. Since the PET/CT findings were discordant with the initial diagnosis, the pathology specimen was reevaluated and with certain immunohistochemical examinations, the final histopathological decision was changed to epithelioid hemangioendothelioma (EHE). In this report, we discuss the FDG uptake pattern in a patient with hepatic EHE and emphasize the importance of dual-time-point hepatic FDG-PET/CT imaging.
