Abstract:
:Schwannomas of the brain parenchyma are extremely rare, occurring mostly in children and young adults. Fewer than 50 cases have been reported in the English-language literature. Isolated temporal lobe epilepsy is a rare presentation of intracerebral schwannomas, with only 2 reported cases. The authors present the case of a 51-year-old woman with a 4-year history of medication-refractory seizures, which were localized on electroencephalography to the right temporal lobe. Magnetic resonance imaging identified a mildly space-occupying, T2 hyperintense, and inhomogeneously enhancing mass in her left mesial temporal lobe. Histological, immunohistochemical, and electron microscopy examinations of the surgical specimen established a diagnosis of intracerebral schwannoma. Accurate diagnosis of intracerebral schwannomas is essential, particularly in younger patients, given the lesions' nature, amenity to resection, favorable long-term prognosis, and broad radiological differential. The etiology of these lesions remains unknown, and multiple proposed theories are reviewed.
