Özet

The authors present the case of a 20-year-old woman with right-sided temporal intraparenchymal meningioma originating from underlying meningioangiomatosis. The patient manifested temporal-type seizures as the initial symptom. She had no stigmata of neurofibromatosis Type 2. Neuroradiological studies revealed an intraaxial, contrast-enhancing lesion in the right temporal lobe. After gross-total removal of the tumor, histological examination revealed a transitional meningioma with surrounding neural parenchyma and features of meningioangiomatosis. Although there were no signs of anaplasia, necrosis, or increased mitosis, tumor islands were observed in the adjacent neuropil. The rare association of meningioangiomatosis and meningioma is discussed, along with radiological and surgical findings.
