Incidental detection of Leydig cell tumor via fluorine-18-Choline PET/CT in a patient with recurrent prostate cancer disease

Clin Nucl Med. 2013 Sep;38(9):752-4. doi: 10.1097/RLU.0b013e31829af8a6.

Abstract

We report a case of a 62-year-old man with biochemical recurrence of prostate cancer disease, investigated by fluorine-18-Choline ((18)F-FCH) PET/CT. (18)F-FCH PET/CT demonstrated focal increased uptake of (18)F-FCH inside the right testis, suggestive for distant recurrent disease. On testis removal, a Leydig cell tumor of 2.5 cm in diameter was unexpectedly found. (18)F-FCH PET/CT may demonstrate tumors other than prostate cancer.
