ROLE OF CT SCAN IN PARTIAL SEIZURES IN CHILDREN.

50 consecutive cases of partial seizures hospitalised over a period of 2 years, were studied. CT Scans were done once at presentation and thereafter cases were followed up with repeat CT scans to evaluate treatment response wherever a treatable cause was found. CT scan diagnosis was correlated with clinical signs and other baseline investigations including an EEG. CT scan abnormality was detected in 66% cases. Single or multiple tuberculomas were noted in 24% cases, cortical atrophy in 14% cases, focal calcification in 10%, haemorrhage in 3% and subdural effusions in 2%. With positive clinical signs, 81% of CT scans were abnormal. 20% of patients with partial seizures having no clinical signs and normal base line investigations including an EEG, had a CT scan abnormality mainly a tuberculoma.
