Cystic Meningioma in the Inter-Hemisferic Space Location

Abstract

Objective: The presentation of cystic meningioma in the inter-hemispheric near the falx cerebri is uncommon. It is difficult to differentiate it from intraaxial tumors, such as gliomas. Therefore, it is likely that it is misdiagnosed as other types of brain tumors. Methods: In this study, we reported a cystic meningioma case in the interhemispheric location, showing an intramural nodule on magnetic resonance imaging scans. Results: Patient underwent surgical treatment and pathological section confirmation revealing meningioma. The patient was a middle-age woman and had been misdiagnosed as suffering from glioma followed by slight hemipharesis on the right extremities. Conclusions: Although this is a rare case, it will be good if we always consider cystic meningioma in inter-hemispheric space when diagnosing this type of cystic lesion if the magnetic resonance imaging (MRI) shows a cystic lesion mimicking glioma image presentation.
