Abstract
Pituitary adenomas are the third most common intracranial neoplasm, accounting for 14.4% in autopsy studies and 22.5% in radiological studies, although only about 10% are symptomatic.

Both are customarily placed under the general category of recurrence. In our study , we have discussed the causes of incomplete resection of pituitary adenoma after endoscopic endonasal trans-sphenoidal removal and factors favoring the outcome such as bony work, surgeon`s experience, size of the tumor, cavernous sinus invasion and the avoidance of the diphragma sellea descending
