Feasibility of endoscopic endonasal resection of intrinsic third ventricular craniopharyngioma in adults.

Intrinsic third ventricular craniopharyngiomas (IVCs) are usually considered as a contraindication of endoscopic endonasal approach (EEA). The aim of this study is to evaluate the safety and feasibility of EEA for the resection of IVCs based on MRI topographical diagnosis and surgical findings. We reviewed the data of 22 patients who were diagnosed to be IVCs according to five MRI criteria and underwent surgery through EEA.
