title: FDG PET differentiation of tumor recurrence from post-stereotactic radiosurgical scar in a central neurocytoma.
abstract: Central neurocytoma is a rare benign tumor of neuronal origin. The tumor is often located in the ventricular system and can proliferate within the ventricle. Five months after stereotactic radiosurgery for recurrent neurocytoma, a 33-year-old woman had a 2.0-cm lesion in the right third ventricle on the MRI. FDG PET demonstrated intense uptake of the lesion. The subsequent MRI follow-up showed growth of the lesion and confirmed recurrence.
