Occipital lobe epilepsy was presented in a patient with intracerebral schwannoma: a case report and literature review.

Schwannoma arising within brain parenchyma is a rare scenario. So far, only 70 cases were reported. We reported a case of intracerebral schwannoma presented with occipital lobe epilepsy, which has never been reported before. A 19-year-old man suffered from intermittent blurred vision and headache. Neuroradiological findings showed a left occipital lesion with cystic and solid components. Histological and electron micrograph features confirmed the diagnosis of schwannoma after the tumor was totally removed. The theories and literature related to this case were reviewed and the possible developmental origin was discussed. We found that this kind of schwannoma is more often in adolescent and young adults.
