a case of childhood-onset giant cell tumor that caused optic nerve atrophy in both eyes

Purpose: The purpose of this study was to report the case of a female patient who had a giant cell tumor in the paranasal sinus during childhood, and while undergoing multiple resection surgeries experienced optic atrophy in both eyes. Case Presentation: This study involved a 35-year-old woman who was previously diagnosed with a giant cell tumor of the paranasal sinus bone at age 13. A CT scan revealed a large tumor extending from the sphenoid sinus to the ethmoid sinus. At age 14, a tumor resection was performed in conjunction with radiation therapy. However, after resection and radiation therapy there were repeated recurrences, and additional resections were performed. Ophthalmically, there was marked optical atrophy in both eyes, and Goldmann visual field perimetry revealed that only the arcuate peripheral area remained on the nasal side of the right eye, and that there were dark spots in the paracentral area of the left eye. Conclusions: In this case, a large giant cell tumor occurred in the sphenoid sinus and ethmoid sinus during childhood, and it is thought that optic atrophy was caused by compressive optic neuropathy. The sphenoid sinus and ethmoid sinuses are anatomically close to the optic nerve, and when a tumor grows larger at this site it can easily put pressure on the optic nerve. Therefore, early detection and treatment are important.
