Anaplastic Meningioma Presenting as a Left Parietal Mass: A Case Report

BACKGROUND Meningiomas are slow-growing tumors attached to the dura mater and are composed of neoplastic meningothelial cells. The tumors are most commonly located in convexities, and it is relatively rare to find such a growth in the parietal region such as the one presented in this case report. CASE REPORT Because of its uncommon presentation, we hereby report the case of a 67-year-old, previously healthy, white Lebanese female patient who presented with forgetfulness, unsteady gait, right-sided motor weakness, and dysphagia. She was found to have an anaplastic meningioma located in the left parietal lobe that was treated by surgical resection. The patient had an uneventful postoperative course, and was stable at later follow-ups. CONCLUSIONS This case report describes the clinical presentation, pathological findings, and the prognosis of this mass, which is atypical in this location, and has been rarely reported in the literature. We also review the literature on anaplastic meningiomas.
