Bilateral Multiple Orbital Metastases Successfully Treated with Standalone Stereotactic Radiosurgery: Clinical Image.

Abstract

Bilateral orbital metastases are extremely rare, and no previous literature has reported bilateral multiple orbital metastases treated with stereotactic radiosurgery (SRS). We present the impressive images of a patient with history of metastatic leiomyosarcoma with newly diagnosed bilateral multiple orbital metastases. The pre-SRS magnetic resonance imaging (MRI) showed 1 right and 2 left orbital metastatic lesions. The patient underwent SRS, and the post-SRS MRI at 2 months showed a decrease in size of the treated lesions. The positron emission tomography scan at 5 months after the treatment showed no avid F-fluorodeoxyglucose uptakes in the 3 orbital metastases. The presenting symptoms were all improved after the treatment with no adverse effects from the SRS. Our interesting images show the presence of multiple lesions in the orbital spaces with excellent treatment response post SRS. This is the first report of a patient who has bilateral and multiple orbital metastases that were successfully treated with standalone SRS.
