Atypical bilateral orbital metastases of lobular breast carcinoma.

Breast carcinoma metastasizing to the orbit is a well-recognized entity. The authors present a 50-year-old woman with bilateral upper and lower eyelid masses and generalized dysmotility. MRI showed gadolinium-enhancing homogenous soft tissue masses filling both orbits from the eyelids to the apex and a biopsy that confirmed metastatic breast carcinoma. To the authors' knowledge, orbital metastasis of breast carcinoma has never presented in this manner.
