(11)C-Choline-Avid but (18)F-FDG-Nonavid Prostate Cancer with Lymph Node Metastases on Positron Emission Tomography.

Choline is a new positron emission tomography (PET) tracer useful for detection of prostate cancer and metastatic lesions. We report a 70-year-old man with prostate cancer and multiple abdominal, pelvic, and inguinal node metastases. PET scans demonstrated accumulation of (11)C-choline in the primary tumor and lymph node metastases but no accumulation of (18)F-FDG. Choline PET/computed tomography may be useful for diagnosis of advanced prostate cancer with suspected metastatic lesions and treatment planning.
