Multiple distinct intracranial tumors: association of pinealoma and craniopharyngioma. Case report.

We report the case of a patient with multiple primary brain neoplasms. A pinealoma was treated with radiotherapy and surgical resection in 1983. In 1987, a craniopharyngioma was resected surgically. Various possible determinants of multiple brain tumors have been described in the literature and are discussed. The possibility of an unknown underlying pathologic mechanism predisposing to multiple malignancies must be considered, but we are unable to conclude that this particular occurrence is more than a random chance finding.
