Randomized prospective study of outcome of short term antiepileptic treatment in small single enhancing CT lesion in brain.

The study was conducted in 81 patients of epilepsy with small single enhancing CT (SSECT) lesion in brain to determine the clinical profile and duration of antiepileptic drugs (AEDs) treatment. The patients were randomly divided into group A (41 cases) and group B (40 cases). Group A patients were treated for 6 months and group B for 1 year with AEDS without cysticidal drugs. The most common mode of presentation was simple partial motor seizures with secondary generalization in both the groups. Repeat imaging of brain (CT/MRI) at 6 months showed disappearance of lesion in 82.94% in group A and 87% in group B, while persistence of lesion was present only in 4.87% in group A and 5% in group B. 87.81% patients in group A and 87.17% in group B were seizure free. The recurrence of seizure occurred in 12.19% cases in group A, and 12.82% in group B. 80% of these patients had calcified lesion in both the groups. This study reveals that SSECT lesion with epilpesy is a benign self-limiting disease. It also reveals that 6 months AED treatment is as effective as one year treatment. Patients having calcified lesion or persistence of lesion might require long term AED treatment.
