A 17-month-old child had typical infantile spasms (IS) in association
with a frontal lobe tumor. EEG showed hypsarrythmia, and typical IS we
re documented by video-EEG monitoring (no focal features were identifi
ed). Seizures ceased after surgical removal of the tumor, a gangliogli
oma. We investigated the role of surgery in infants with West syndrome
(WS) and lesions of various types.
