Abstract

Meningioma is one of the most common types of benign primary brain tumors in older adults, and multiple meningiomas are reported in fewer than 1% to 10% of cases. However, there is no definitive treatment guideline for patients with multiple meningiomas. An 80-year-old man presented with abruptly impaired cognition and was found to have two distinct meningiomas located in the temporal and frontal lobes. A single frontotemporal craniotomy was performed to remove both tumors. Pathological analysis revealed different subtypes and World Health Organization grades for each mass. The patient showed symptomatic improvement, experienced no postoperative complications, and exhibited no signs of recurrence during a 1-year follow-up period with evaluations at 3-month intervals. Despite the absence of a standard treatment for multiple meningiomas, surgical resection in a single procedure is feasible in selected patients.
