BackgroundSpindle cell oncocytomas are extremely rare neoplasms of the sellar, parasellar, and suprasellar regions that can frequently mimic pituitary adenomas. Fewer than 50 cases have been ever reported in the literature, and there is no consensus on best treatments to be provided.Case DescriptionWe hereby present a challenging case of sellar and suprasellar spindle cell oncocytoma in a patient of 64 years. The patient, who presented with hydrocephalus, hypopituitarism, and visual deficit, underwent urgent transsphenoidal (TNS) resection of the mass, which was aborted for massive life-threatening bleeding. The patient received ventriculoperitoneal shunt with relief of symptoms. An endovascular embolization of tumor feeders from the distal portion of the right internal maxillary artery, in particular the sphenopalatine artery, was then performed and a second-look TNS surgery was feasible. The patient was discharged in optimal clinical condition, recovered both endocrinologic and visual deficits, and is now in follow-up.ConclusionsWe found that the oncocytoma was radiologically and clinically comparable with a pituitary adenoma, except for higher representation of vasculature. According to our recent experience and review of the literature, we believe that surgery (transsphenoidal or transcranial approach) is the recommended treatment in those who are symptomatic and preoperative embolization might be a suitable option to reduce intraoperative bleeding and increase radicality.Copyright © 2020 Elsevier Inc.
