Intracranial tumors of different histologic types infrequently affect patients with pituitary adenomas and no history of head irradiation. The association with craniopharyngioma is extremely rare. Aims of this paper are: (1) to provide a critical literature review of typical features of pituitary adenoma presenting in association with craniopharyngioma; (2) to describe the first documented (clinically, biochemically, histologically, and radiologically) case of aggressive, suprasellar papillary craniopharyngioma presenting with amenorrhea, progressive reduction of visual field, and severe headache in a 38-year-old woman, a decade after surgical cure for microprolactinoma associated with empty sella, during which she had carried two pregnancies; and (3) to discuss common etiopathogenetic mechanisms, in relation to the management of these lesions. Systematic literature search for English literature focusing on the association of craniopharyngioma and pituitary adenoma was performed using PubMed database. Additional relevant articles from references lists were also included. Clinical, laboratory, and radiological examinations performed in our patient for the two brain lesions at diagnosis and follow up were collected. Literature search retrieved nine articles. Typically, craniopharyngioma were of adamantinomatous type, occurred simultaneously to pituitary adenoma, presented with headache and visual loss, and affected men. No case of clearly documented metachronous lesion affecting a woman after pregnancy had been described before. Although very rare and with uncertain etiopathogenesis, second tumors (i.e., craniopharyngioma) should be considered in patients with a history of pituitary adenoma, presenting with suggestive signs and symptoms, even after a long disease-free period, in order to provide proper and prompt treatment.
