Contribution of Intrasellar Pressure Elevation to Headache Manifestation in Pituitary Adenoma Evaluated With Intraoperative Pressure Measurement

Abstract

Headache in patients with pituitary adenomas associated with ISP elevation, results from compromised dural integrity at the sella and intratumoral hemorrhage. The increased stretch force of the sella dura may be a notable etiology of headache in patients with pituitary adenoma.
