Focal hepatic 11C-acetate activity on PET/CT scan due to lymphoid hyperplasia

Clin Nucl Med. 2015 Mar;40(3):278-81. doi: 10.1097/RLU.0000000000000634.

Abstract

A 69-year-old woman complaining of abdominal bloating underwent ultrasonography, which revealed a small lesion in the left lobe of the liver. The lesion had elevated activity of both 18F-FDG and 11C-acetate on PET/CT scan and was suspected of being malignant. Postresection pathological examination demonstrated that this lesion was a focal intrahepatic lymphoid hyperplasia.
