Multiple meningiomas are generally uncommon, and the incidence is approximately 1-2% of all meningioma cases. A 63-year-old female patient complained of an episode of unconsciousness. Neurological examina-tion revealed choked discs and left homonymous hemianopsia. Plain craniograms showed multiple calcifications in the right hemicranium. Right carotid angiography revealed abnormal vessels and multiple tumor stains. Computerized tomographic scans confirmed the existence of multiple high-density tumors in the frontal lobe, sphenoidal ridge, parasellar region, middle fossa, and occipital region, all within the right hemicranium. Surgery was performed in three stages; the frontal, sphenoidal, and parasellar meningiomas were removed in the first stage, the occipital tumors were removed in the second, and the middle fossa tumors were removed in the third. Postoperatively, slight disorientation and left hemiparesis were recognized, but the patient was discharged with fair recovery.
