title: [Primary cerebral lymphoma diagnosed by the ophthalmologist].
abstract: METHODS
  A 20-year-old male, HIV positive, with myodesopsias (floaters) in both eyes for two weeks. Fundus examination revealed bilateral papillary oedema with peripapilar flame-shaped haemorrhages. The neuroimaging tests showed a cerebral mass in the left parietal lobe. The biopsy confirmed the diagnosis of lymphoid neoplasm.
  
  
  CONCLUSIONS
  Primary lymphoma is the most common malignancy of the central nervous system (CNS) in AIDS patients, although highly active antiretroviral therapy has reduced its incidence. The ophthalmologist plays an essential role in the diagnosis of CNS neoplasm.
