Intracranial gangliogliomas.

Five cases of intracranial gangliomas in their clinical, diagnostic and surgical aspects are presented. In four cases we arrived at the diagnosis by CT-scan, which showed in all of them, calcified lesions without a mass effect. Total surgical resection was performed in four cases, and there is no evidence of recurrence either clinically or in the CT-scan after different follow-up periods. Although infrequent, these kinds of tumours should enter the differential diagnosis at any time when there a calcified mass exists in children or young patients with a long history of seizures. In our experience, seizures were the most important sign in all cases with supratentorial gangliogliomas.
