title: Intrasellar paraganglioma associated with hypopituitarism.
abstract: A 37-year-old with a history of postpubertal arrest of sexual development and delayed growth was found to have an enlarged sella turcica. The clinical and biochemical features were consistent with hypopituitarism. A tumor was removed transsphenoidally that, through light microscopy, histochemistry, and electron microscopy, proved to be a paraganglioma. We report the possible origin of intrasellar paraganglioma, as well as the pathogenesis of hypopituitarism.
