Tuberous sclerosis complex with unilateral perisylvian polymicrogyria and contralateral hippocampal sclerosis - a...

Malformations of cortical development (MCD) encompass a wide spectrum of brain disorders. Although rare, the combination of certain MCD may occur. We report a rare case of combination of three distinct cerebral pathologies: tuberous sclerosis, polymicrogyria and hippocampal sclerosis in a patient with intractable epilepsy. Ictal EEG and ictal SPECT suggested right perisylvian area as a seizure onset zone. However, on MRI multiple potentially epileptogenic lesions were identified. The neurobiological background of the coexistence of different types of malformations of cortical development remains enigmatic.
