There are also cortical and subcortical atrophic cerebral and cerebellar changes with the consecutive widening of subarachnoidal space, and a few retrocerebellar subarachnoidal cysts (differential diagnosis) up to 40 mm.

Case Discussion

The patient had the first seizure during the sleep when he was 7. MRI brain performed at that time was reported as normal.

Another seizure occurred 8 years later with the head deviation to the left, upward eyes deviation and clonic extremities movements for about 2 minutes. He then had another MRI brain and was diagnosed with mesial temporal sclerosis.

Since then, he is on the antiepileptic therapy and had no more attacks. EEG is normal. He is physically and mentally adequately developed.
