MRI features highly suggestive of a focal cortical dysplasia with associated ipsilateral hippocampal sclerosis, type IIIa according to Blumcke classification of focal cortical dysplasia.

Focal cortical dysplasias (FCD) represent a heterogeneous group of disorders of cortical formation, which may demonstrate both architectural and proliferative features. They are one of the most common causes of epilepsy and can be associated with hippocampal sclerosis (as in this case) and cortical glioneuronal neoplasms.
