 Pituitary adenoma presenting with infra-sellar extension into the sphenoidal sinus are frequent,but extension to the nasal cavity and nasopharynx is very rare. We report herein two cases of pituitary adenomas in which the initial clinical signs were unconsciousness and visual disturbance. CT and MRI showed bone defect at the base of the frontal skull base and giant pituitary adenoma invading the nasal cavity. Intranasal endoscopic biopsy was performed and the diagnoses were made by histological examination and measurement of serum hormone levels. Patients were treated for resction of tumors by neurosurgeon. We thought that it is important to consider skull base tumors,if patients have nasal cavity masses with optical disorders.
