Intense PSMA Uptake in Solitary Fibrous Tumor of the Seminal Vesicle

Abstract

Solitary fibrous tumor arising from the seminal vesicle is very rare. We describe 18F-PSMA-1007 PET/CT findings in a case of prostate adenocarcinoma with a solitary fibrous tumor of the left seminal vesicle. The solitary fibrous tumor showed intense 18F-PSMA-1007 uptake mimicking metastatic prostate adenocarcinoma. This case indicates that solitary fibrous tumor may cause false-positive result when using PSMA PET in staging of prostate cancer.
