Recurrent meningeal sarcoma successfully treated with stereotactic radiosurgery

Primary intracranial meningeal sarcoma is a rare neurological malignancy without strong evidence-based treatment guidelines. The authors describe a boy with primary meningeal sarcoma who symptomatically presented at 10 months of age and was treated with primary resection. The patient had multifocal recurrence approximately 2 years later. Given the location and rapid progression of the disease, the boy was treated with gamma knife surgery. He had a complete radiographic response 3 years posttreatment. He attends school full time and enjoys good quality of life. Based on local control and response to radiosurgery, the authors suggest that multifocal meningeal sarcomas not amenable to resection can be effectively managed with stereotactic radiosurgery.
