Abstract
Purpose: We aim to more fully understand the incidence and natural history of spontaneously resolving non-functioning pituitary adenomas (NFPAs).Methods: We report a case of spontaneous complete resolution of a NFPA revealed by preoperative magnetic resonance imaging. In addition, we searched all major databases and neurosurgery journals to perform a comprehensive literature review of all previously reported cases of spontaneously resolving NFPAs. We discuss how these cases may contribute to our understanding of the natural course for non-functional pituitary adenomas.Results: To date, only twelve cases of spontaneously resolving nonfunctional pituitary adenomas have previously been reported. The presented case is the first reported spontaneously resolved nonfunctioning pituitary adenoma to recur. In all cases, apoplexy resulted in resolution of mass effect, obviating the need for surgical decompression.Conclusions: In all NFPA cases, the preoperative MRI should always be studied closely before surgery is initiated. Additionally, because we have demonstrated that the adenoma may regrow after spontaneous regression following apoplexy, these patients should be followed with regular serial MRIs to monitor for recurrence.
