Abstract
We report a case of a 68-year-old woman with a sphenoid sinus chondroni a. The patient was admitted to Showa University Hospital after experiencing visual disturbauce for three months. CT films of the facial bone showed a tumorous lesion with calcification that filled the sphenoid sinus. MRI T1-weighted image showed a mosaic pattern and a low-density tumor in the sphenoid sinus. The tumor was determined to be a chondroma, pathologically. We decided to perform intracapsular enucleation, using the transnasal approach, because of the age and general status of the patient and the location of the tumor. During the procedure, we identified the optic nerve through the capsule. Therfore, to protect this nerve, we resected the tumor intracapsullarly. No significant complications were observed. No recurrence has been observed for 8 years since the operation.
