Temporal Sclerosis
A 16-year-old patient with temporal lobe epilepsy underwent selective amygdalohippocampectomy when his recurrent seizures became intractable and not responsive to antiepileptic medication. Magnetic resonance imaging (MRI) of his brain revealed parenchymal volume loss of the left hippocampus that was consistent with mesial temporal sclerosis, so it was felt that the patient could have complete seizure control with surgery. How should this case be coded? ...
