Case contributed by Ivan Kulikov

Presentation

Seizures with loss of consciousness when falling asleep. Clonic cramps in the extremities, with paralysis of the right hand (Todd's paralysis), duration of about 2 minutes. Electroencephalogram: epileptiform patterns in the left frontal-temporal region

Patient Data

Age: 9 years
Gender: Male
MRI

There is an abnormal vertical orientation of the hippocampal body and collateral sulcus.

Case Discussion

An asymmetric hippocampus should be differentiated from structural variational of the normal medial temporal lobes, however, given the presence of clinical symptoms this is most likely hippocampal malrotation.
