Treatment of meningioma in a patient with congenital immunodeficiency disorder.

We treated a patient with meningioma suffering from a congenital immunodeficiency syndrome. The patient was diagnosed with common variable immunodeficiency (CVID) in youth, and had suffered from repeated infections, especially in the respiratory tract, requiring continuous treatment with antibiotics. Imaging revealed a tumor located in the left frontal region with a broad attachment suggesting meningioma in the convexity dura mater. Gammaglobulin was infused intravenously preceding the operation and serum gammaglobulin was controlled at over 400 mg/dl and then a Simpson grade 1 operation was performed. The patient did not show any complications in infectious susceptibility, and there was no recurrence of the tumor in the 5 years following the operation. The surgical risk for CVID patients in the neurosurgical field is still not clear, but we could maintain the condition of the patient by controlling the serum gammaglobulin level in the perioperative period.
