Uncommon Penio-Scrotal Metastases of Prostate Cancer Detected on 68Ga PSMA PET/CT

Clin Nucl Med. 2019 May;44(5):424-425. doi: 10.1097/RLU.0000000000002527.

Abstract

A 68-year-old man, a known case of carcinoma prostate (Gleason score 4 + 4), status post transurethral resection of prostate cancer and radiotherapy, on hormonal treatment with rising prostate-specific antigen 9.0 ng/mL and penile swelling underwent Ga-PSMA PET/CT scan for metastatic workup and restaging. The study revealed abnormal tracer uptake in the prostatic bed region, the pelvic and inguinal lymph nodes, and metastases to the glans of penis and scrotum. The penile and scrotal lesion was proved to be metastatic adenocarcinoma from prostate on fine-needle aspiration cytology.
