56 year old female with a history of progressive Multiple Sclerosis developed a medically intractable seizure disorder. The patient was tried on a combination of multiple antiepileptic medications without improvement.

The patient underwent seizure “mapping” with a seizure focus being localized to her right temporal lobe. She underwent a successful surgical temporal lobectomy with improvement in the seizure pattern.

On the CT image above note a practically absent temporal lobe on the right.

The patient did experience some cognitive and memory decline as a result of this surgery.
