Retro-Orbital Metastasis From Breast Cancer: An Uncommon Site!

We report the case of a 65 year old lady who presented with symptomatic retro-bulbar metastasis from breast cancer at first presentation. This was diagnosed on CT of the orbit and confirmed on biopsy. She was also found to have widespread metastatic disease elsewhere and had systemic treatment in the form of cytotoxic chemotherapy to which the tumour showed a good response. There are only a handful of cases of orbital metastases in the literature, and of these, retro-bulbar tumours are even rarer. There is no report to date of simultaneous presentation of breast primary and symptomatic secondary in the retrobulbar region.
