Core Tip

Core tip: Neuroendocrine tumors are rare neoplasms that only uncommonly metastasize to the orbit. Given these tumors are associated with prolonged survival despite dissemination, maintaining quality of life by providing early diagnosis and effective treatment to preserve vision and comfort is a fundamental issue. We report the case of a patient who 2 years after the diagnosis of metastaic neuroendocrine tumor to the liver presented with right-sided diplopia. She was found to have metastatic neuroendocrine tumor to the right orbit and was successfully treated with radiotherapy. Eighteen months later, she remains well and with no visual loss.
