Paraneoplastic Optic Neuropathy in a Patient with a Non-Small Cell Lung Carcinoma: A Case Report

Abstract

PURPOSE: To report a case and describe the clinical approach to a patient with a non-small cell lung carcinoma and paraneoplastic optic neuropathy. METHODS: Case report. RESULTS: A 79-year-old woman with known non-small cell lung carcinoma was admitted with a swollen optic disc in the right eye. After detailed clinical, laboratory, and imaging studies, the authors diagnosed paraneoplastic optic neuropathy, excluding other possible diagnosis. CONCLUSIONS: Paraneoplastic optic neuropathy is a clinical challenge and should be considered as a possible diagnosis in every cancer patient with optic disc edema.
