| ABSTRACT |
|
Ectopic pituitary adenoma, occurring outside the sella turcica without any continuity with intrasellar pituitary gland is very rare. So far, less than 90 such cases have been reported in the literature. Regarding to ectopic locations, suprasellar region, sphenoid sinus and clivus have been reported in decending order of frequency. To our best knowledge, growth hormonesecreting ectopic pituitary adenoma in the clivus has never been reported. With the pertinent literature review, we present our unique case with its characteristic magnetic resonance imaging and immunohistochemical features. |
