Abstract

Purpose

To report a case of a female patient treated with stereotactic radiosurgery for compressive optic neuropathy by recurred maxillary cancer.

Case summary

A 51-year-old woman with a history of maxillary cancer presented with decreased visual acuity and visual field and color vision defects in the right eye. The CT scan revealed a wide spread mass along the ethmoid sinus, orbit, optic canal, and skull base. Under the impression of compressive optic neuropathy, stereotactic radiosurgery was performed. A cumulative dose of 39 Gy in 3 daily fractions of 13 Gy was administered to the mass. After 10 days, visual acuity, color vision, and visual field improved and were maintained after a 2 month follow-up.

Conclusions

Stereotactic radiosurgery could be another treatment option for patients with compressive optic neuropathy caused by a malignant tumor.
