title: Paraneoplastic optic neuropathy in a patient with a non-small cell lung carcinoma: a case report.
abstract: OBJECTIVE
  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.
