Spindle cell oncocytoma is a rare nonfunctioning neoplasm of the adenohypophysis, and was first described in 2002 by Roncaroli et al. In 2007, spindle cell oncocytoma has been categorized as a separate entity by the World Health Organization (WHO) and is classified as a Grade 1 tumor of the central nervous system. Spindle cell oncocytoma of pituitary gland usually occurs in adults and accounts for 0.1-0.4% of all sellar region tumors. Clinically and radiologically, they are indistinguishable from nonfunctioning pituitary adenomas. From 2002 to 2018, approximately 46 cases of spindle cell oncocytoma of pituitary gland had been reported in the English literature and we would like to report a case of 28-year-old woman presented with pituitary apoplexy proved to be a case of spindle cell oncocytoma of pituitary gland which probably will be the 47th reported case.
