Abstract
Malformations of the diaphragma sellae may permit transdiaphragmatic cerebrospinal fluid pulsations that lead to expansion of the sella turcica. The purpose of this report is to describe an intrasellar arachnoid cyst observed during surgery being filled by the action of an apparent one-way valve.
