Summary Medically intractable epilepsy (MIE) resulting from postinfectious etiologies requiring surgery have been uncommonly reported. A series of 28 cases are presented (hospital prevalence 5.7%). The mean duration of epilepsy prior to surgery was 8.2 ± 2.1 years. The mean time of onset of epilepsy after central nervous system infection was 1.4 ± 0.9 years (range 0–19 years). The pathologies included postpyogenic meningitic/encephalitic sequel (8), neurocysticercosis (6), tuberculomas/posttuberculous etiology (4), postpyogenic abscess of otogenic etiology (4), posttraumatic abscess–related gliosis (2), and gliosis of unknown infectious etiology (4) cases. Surgery included mesial temporal (11), lateral temporal (4), frontal (9), parietal (2) resections and hemispherotomy (1). Hippocampal sclerosis was seen in nine cases (4 neurocysticercosis) and this occurred in younger persons as compared to neocortical epilepsies. Good outcome (Engel class I and II) was seen in 23 of 28 cases (Engel class I in 17).
