Penile Metastasis From Prostate Cancer Detected by 18F-Fluorocholine PET/CT

F-18-Fluorocholine (F-18-FCH) PET/CT is widely used to study patients affected by prostate cancer. F-18-FCH PET/CT is suitable for the detection of pelvic and abdominal nodal and skeletal metastases. Indeed, F-18-FCH PET/CT sensitivity for other organs, such as the liver and the urinary tract, is lowered by the radiopharmaceutical urinary washout and intense liver uptake. Herein, we report the case of a patient affected by oligometastatic prostate cancer in good clinical condition treated with total androgen blockade. F-18-FCH PET/CT showed a diffuse and intense uptake in the shaft of the penis, which was an evidence of a rare penile metastasis.

Automated summary

F-18-Fluorocholine (F-18-FCH) PET/CT is commonly used for prostate cancer patients, but its sensitivity for certain organs may be limited. This case report describes a patient with oligometastatic prostate cancer and a rare penile metastasis detected through F-18-FCH PET/CT.
