Intracavernous Schwannoma Characterized With F-18-FDG, Ga-68-DOTATOC, and F-18-Choline PET
CLINICAL NUCLEAR MEDICINE(2022)
Abstract
We report the case of a 75-year-old man with history of prostate cancer whose left intracavernous lesion was successfully characterized by 3 PETs performed successively with different tracers. This poorly characterized tumor was initially discovered on an MRI conducted to investigate an acute diplopia and slowly growing during follow-up. On 18F-FDG PET, the lesion showed no significant uptake, and no extracranial lesion was found nor did it have increased 68Ga-DOTATOC uptake. Finally, this tumor displayed a high 18F-choline uptake, and no extracranial lesion was revealed with this tracer. The diagnosis of schwannoma without malignancy criterion was proven by biopsy.
