The presence of dysmorphic neurons with strong cytoplasmatic accumulation of heavy non‐phosphorylated neurofilament is crucial for the diagnostics of focal cortical dysplasia type II (FCDII). While ...ILAE's classification describes neocortical dysplasias, some groups have reported patients with mesial t abnormal neurons in the hippocampus of mesial temporal lobe epilepsy. Here we report a patient with such abnormal neurons in the hippocampus and compared it with previous reports of hippocampal dysplasia. Finally, we discuss the need for diagnostic criteria of hippocampal dysplasia.
