摘      要：Neuroendocrine tumors are rare neoplasms that infrequently metastasize to the *** that patients with these tumors may have prolonged survival despite dissemination,maintaining quality of life by providing early diagnosis and effective treatment to preserve vision and comfort is a fundamental *** report the case of a79-year old woman who presented with well-differentiated metastatic neuroendocrine tumor to the liver with no carcinoid syndrome and was started on intramuscular long-acting octreotide with disease *** years later she developed right-sided diplopia associated with mild eye discomfort,proptosis and *** magnetic resonance imaging showed a 2.1 cm mass in the right orbit and further biopsy confirmed a neuroendocrine tumor *** patient was treated with a four-week course of stereotactic radiotherapy to the right orbital metastasis(4000 cGy in 20 fractions)with minor conjunctivitis as the only side *** months later,she remains well with no visual loss.
