Abstract Paragangliomas arising in the sellar region are rare. We report a case of intrasellar paraganglioma of a 54-year-old man who presented with gradually decreasing visual acuity. Physical examination revealed bitemporal hemianopsia with no apparent signs of endocrinologic dysfunction. Magnetic resonance imaging revealed a large sellar mass believed to be a nonfunctioning pituitary adenoma. The tumor was removed transsphenoidally and submitted for histologic examination. The morphologic features, based on histologic, immunocytochemical, and electron microscopic analyses, were consistent with the diagnosis of paraganglioma. The diagnostic morphologic features and the immunocytochemical profile of the tumor are reported.
