Magnetic resonance imaging of mesial temporal sclerosis: case reports

Two patients with uncontrollable complex partial seizures had normal findings on pre- and postinfusion computed tomography scans. Magnetic resonance imaging demonstrated, in both patients, a lesion in the temporal lobe suggestive of mesial temporal sclerosis. One patient underwent temporal lobectomy, and the radiologic diagnosis was verified. In patients with complex partial seizures, magnetic resonance imaging appears to be able to noninvasively localize temporal lobe lesions in preparation for surgical intervention.
