Abstract

Adenomas are the most frequent hypophyseal tumors, and they can be occasionally located outside the sella turcica, either by growth from it or, less frequently, by ectopic location. The case of a 56 year old female is presented, in which a brain TC prescribed in the context of a vertiginous syndrome revealed a lesion located in the sphenoid region extending to the clivus. Several diagnoses were discussed: chordoma, nasopharyngeal carcinoma, minor salivary gland derived tumor, and metastatic tumor. The lesion was surgically approached and excised, and it was finally demonstrated to be an ectopic hypophyseal adenoma.
