Superior Orbital Fissure Syndrome in a Case of Breast Cancer.

Metastasis from breast cancer to the head and neck region is a rare occurrence. However, of all the cancers that metastasise to the orbit, breast cancer is the leading cause in women. Usually, breast cancer metastasises to the fat and muscles in the orbit, and involvement of the bony orbital wall is rare. We report a case of a 52-year-old woman who presented with metastasis to the left greater wing of the sphenoid and adjacent squamous temporal bone. Ophthalmoplegia and proptosis were the initial manifestations in this patient, which lead to the diagnosis of the underlying breast cancer.
