Abstract
- A 67-year-old male presented with papilledema and back pain localized to the T10 level. Initial workup revealed multifocal spinal ependymoma which was resected and treated with external beam radiotherapy. Nine years after treatment, the patient had a relapse of back pain, and MRI was inconclusive in distinguishing posttreatment radiation necrosis from recurrent tumor. We present the first described report with the utilization of multiparametric positron emission tomography-magnetic resonance imaging and perfusion MRI to distinguish recurrent spinal ependymoma from radiation necrosis.
