Abstract
Pituitary tumors are usually benign adenomas presenting as space occupying lesions in the sella turcica. Rarely these tumors may present beyond the sella either as an extension of the primary tumor or tumor arising from an aberrant pituitary location. One such extra sellar extension or origin of these tumors is in the olfactory spaces, comprising of 2% of all the nasal tumor. Because of the rarity of lesion and sometimes nonfunctional nature of the tumor, these may present diagnostic problems to the otolaryngologists and are diagnosed as polyps or nasopharyngeal malignant tumors. Measurement of pituitary hormones may provide a clue to the diagnosis in cases of paranasal polyps or rhinorrhea as it may change the management in such cases. We present here a case of a patient with an invasive pituitary adenoma who had presented in the Department of Otorhinolaryngology with epistaxis.
