A 57-year-old man with a history of multiple recurrent atypical meningiomas (World Health Organization grade II) had several surgical resections including γ knife resection of the parafalcine meningioma, followed with a stereotactic radiosurgical ablation. Despite these treatments, an MRI scan performed 7 months later showed progression of the disease. The patient remained symptomatic with intermittent severe headaches associated with nausea, vomiting, and visual disturbance. He had a positive In-pentetreotide indicating the presence of somatostatin receptors. Therefore, he was placed on systemic Sandostatin (octreotide acetate) treatment, and at follow-up, he was clinically responsive to treatment.
