title: Coexisting intracranial tumors with pituitary adenomas: genetic association or coincidence?
abstract: The co-occurrence of two or more brain tumors with different histological features is rare. The authors report three rare cases of intracranial tumors associated with pituitary adenomas. Two of the pituitary tumors were functioning adenomas: a prolactinoma and a thyrotropin secreting adenoma. Two of the associated intracranial neoplasms were gliomas and one was a meningioma. Radiological and clinical examination for syndromal association was negative in all cases. We briefly discuss the presentation and treatment options of these cases and review the 19 previous publications in the literature of pituitary tumors occurring in association with other neoplasms and explore the possible links underlying these co-occurring neoplasms. Our three cases represent 0.86% of all pituitary tumors operated at our institute over a 9-year period.
