Abstract

The case of a 66-year-old man undergoing a staging PSMA PET/CT after a recent diagnosis of prostate carcinoma is presented. In addition to uptake within the prostate consistent with primary tumor activity, mild symmetrical and diffuse uptake is also noted within central zone. The appearance is not consistent with likely tumor activity. Comparison is made with histopathology after a radical prostatectomy, and no correlating tumor is noted in the region of central zone uptake. Increased PSMA uptake within the compressed central zone of the prostate may represent a potential pitfall in PSMA PET/CT imaging.
