Sixty-seven patients with epilepsy and isolated enhancing computed tomography (CT) scan lesion were studied with magnetic resonance imaging (MRI). Fifty-six patients (83.5%) had partial seizures and 11 (16.4%) had generalized seizures. Four distinct groups were identified by MRI: nonspecific 16 cases (23.8%), tuberculoma 38 cases (56.7%), cysticercosis 12 cases (17.9%), and abscess 1 case (1.4%). Patients in the non-specific group had lesions that were hyperintense on T2 images and hypointense or isointense on T1 images. Such lesions resolved completely in 5 months with serial MRIs while the patients were receiving antiepileptic drugs (AEDs). Virologic studies, including cerebrospinal fluid (CSF) serology, are suggested for patients with such MRI lesions.
