Primary Hepatic Angiosarcoma Having FDG Uptake at the Similar Level of the Normal Liver Parenchyma.

Primary hepatic angiosarcoma is a rare but aggressive malignancy. A 60-year-old woman presented with multiple liver lesions with progressive enhancement detected with multiphasic CT. FDG PET did not show any FDG-avid lesions, and the uptake of hepatic lesions was similar to that of the normal liver parenchyma. Subsequently, pathological examination revealed hepatic angiosarcoma.
