Abstract

A 57-year-old woman, known for metastatic breast cancer, presented in November 2020 with a newly left intraorbital metastasis on MRI. The patient had a history of radiotherapy for focal leptomeningeal metastasis surrounding the area (left temporal), receiving 20 Gy in one fraction 7 months before. We irradiated this new metastasis delivering a fractionated stereotactic radiotherapy of 35 Gy in 7 fractions with a Cyberknife® system. The patient started a metronomic chemotherapy schema of Cyclophosphamide (50 mg daily) and Methotrexate (2.5 mg 2x/day) one week before the first day of radiotherapy. The day after the first fraction, she presented a severe left-eye palpebral edema.
