Annotated image

Asymmetry between the mesial temporal lobes with the left atrophic side highlighted in red.

This area corresponds to the hippocampus.

Case Discussion

This asymmetry between the mesial temporal lobes is recognised as mesial temporal sclerosis.

This is a finding in temporal lobe epilepsy.

If dedicated "epilepsy protocol" scans are performed, this abnormality can be identified and allows better discussion with the patient about prognosis. These epilepsies can be hard to control with medication, but have good results from surgery with resection of the abnormal lobe.
