Abstract:
Meningiomas arise from meningothelial cells that line the arachnoid membrane. So most meningiomas are dural-based lesion. But meningiomas without dural-attachment do occur and are less common. We report our experience of intraparenchymal sylvian fissure menigioma. A 21-year-old female presented with a one-month history of headache that was associated with long-term intermittent partial seizure. CT revealed about 4.5x4.3x5.5cm sized calcified mass with enhancement in right temporal lobe. On MR imaging, the lesion was observed in the right temporal lobe that was low-signal intensity on T2WI and iso-signal intensity on T1WI with well enhancement. Operation was performed via right orbitocranial approach. The internal surface of dura was intact. Tumor was totally removed except the capsule of tumor adhered to main trunk of middle cerebral artery. The histopathology showed meningioma, psammomatous type. Intraparenchymal meningioma should be considered in the differential diagnosis of intraaxial lesions in patients of any age group.
