We report the case of a 50-year-old man, with previous history of grade 3 intracranial hemangiopericytoma with initial complete surgical resection, addressed for local recurrence. Surgical revision performed 18 months after initial surgery allowed only partial resection, leaving residual disease along the optic nerve. Complementary radiotherapy with proton was decided. 18F-FDG PET/CT and 18F-choline PET/CT were both performed for treatment planning. 18F-FDG PET showed no uptake of the residual tumor, whereas 18F-choline depicted highly metabolic residual disease uptake with excellent delineation of local recurrence. 18F-choline PET/CT appears as a useful PET tracer for hemagiopericytoma imaging.
