title: Bilateral orbital metastases from a neuroendocrine tumor.
abstract: When neuroendocrine tumors metastasize to the orbit, they usually do so as solitary lesions, sometimes involving an extraocular muscle. A 70-year-old woman with a known neuroendocrine tumor had bilateral painful proptosis, orbital soft tissue swelling, and ophthalmoplegia. Imaging showed masses within all the extraocular muscles. Orbital biopsy disclosed metastatic neuroendocrine tumor cells within the connective tissue.
