Rapid and complete cyst resolution in a case of craniopharyngioma following Gamma knife radiosurgery

Abstract

A case of cystic craniopharyngioma is presented in which multiple micro-surgeries failed to result in cyst resolution and significant enhancement in patients symptoms. Tumor irradiation using Leksell Gamma knife resulted in complete absorption of the remained cystic parts of the tumor and dramatic improvement in patients symptoms three months after the radiosurgery .Possible mechanisms are dis¬cussed.
