A Case of the Intrasellar Arachnoid Cyst with Extension to the Sphenoid Sinus / 대한이비인후과학회지

ABSTRACT

We report a case of intrasellar arachonoid cyst with extension to the sphenoid sinus, which is a very uncommon lesion. Preoperatively, we studied the PNS CT & Brain MRI and these images showed a large cyst in the widened sellar turcica with extension to the sphenoid anterior wall. We planned endoscopic surgery via transnasal-transphenidal approach. The endoscopic surgery was performed with no complication. We reviewed the literature and discussed the treatment of the intrasellar arachnoid cyst.
