Coexisting Pituitary Adenoma and Suprasellar Meningioma: A Coincidence or Causation Effect? Report of Two Cases and Review of Literature

Abstract

Background and Importance: The coexistence of pituitary adenoma and another type of brain tumor is a very rare clinical scenario. Even though such a presentation can be an incidental event but the possible pathogenesis of coexistence of different lesions in the sella and suprasellar region has not yet been elucidated. Case Presentation: Two cases of concomitant sellar and suprasellar region tumors are reported. A 37-year-old lady with Prolactinoma and a suprasellar meningioma and a 42-year-old Acromegalic man with suprasellar meningioma and a pituitary adenoma (PA). Conclusion: Both meningiomas were removed transcranially while the Prolactinoma could be managed medically and the growth hormone (GH) secreting adenoma was removed trans-sphenoidally. The visual problems and hormonal imbalances of both patients improved postoperatively and there has been no sign of recurrence of the lesions after a mean of five years follow up. The literature is reviewed on this topic and the possible pathogenesis and management protocol of similar lesions are discussed.
