Generalized tonic clonic seizure. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears unremarkable. In particular, the hippocampi appear to be grossly intact and there is no evidence of heterotopia, hamartoma, or gross cortical dysplasia. There is no abnormal intracranial enhancement. There is a cavum septum pellucidum and vergae with mildly convex boundaries measuring up to 11 mm in width. The ventricles and basal cisterns are otherwise normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No definite evidence of hippocampal lesions. 2. Mildly cystic appearing cavum septum pellucidum and vergae measuring up to 11 mm in width.
