Gastrointestinal Stromal Tumor Showing Intense Tracer Uptake on PSMA PET/CT

Clin Nucl Med. 2017 Mar;42(3):200-202. doi: 10.1097/RLU.0000000000001491.

Abstract

A 70-year-old man with suspected prostate cancer was referred for Ga-PSMA-HBED-CC PET/CT (short PSMA PET/CT) for staging of tumor extent. Apart from vivid tracer uptake in the prostate gland and osseous metastasis, PSMA PET/CT revealed a large soft tissue mass with calcifications in the left upper abdomen showing intense tracer uptake. Histologic examination revealed the mass to be a gastrointestinal stromal tumor.
