Thalamic intracerebral schwannoma: case report

The intracranial schwannomas cover about 8% of all the brain tumors, although, those localized inside the encephalic parenchyma are rare only 55 cases being reported in the literature. The histhopatologic diagnosis is based on the cellular type and arrangement common to the nervous sheat tumors, the immunohistochemical findings (GFAP, S-100 protein, EMA) and electronmicroscopic findings as well. The clinical presentation related to the intraparenchimatous schwannoma is variable, depending on its localization, the image diagnosis does not show any typical aspect. The surgical treatment is curative once a complete extirpation is obtained. These tumors are benign but one case reported presented malignant signs. We present a patient that had a thalamic schwannoma with histological confirmation. We found no case with this localization in the literature.
