Abstract
Here is a case of an isolated orbital metastasis in a previously diagnosed metastatic breast cancer of a 46-year-old woman presenting diplopia and pain in her left eye. The magnetic resonance showed a suspected metastatic localisation in the upper left oblique muscle, which was confirmed by the fine-needle aspiration biopsy. The systemic therapy with liposomal doxorubicin as well as local stereotactic radiotherapy showed a gradual improvement of the local symptoms and signs.
