title: Epstein-Barr Virus DNA quantification: an adjunctive diagnostic marker for AIDS-associated lymphoma.
abstract: We report an HIV-positive patient who developed a unilateral retinitis and subsequent intracranial lesions. The finding of Epstein Barr virus (EBV) DNA at a > 1-log greater concentration in the vitreous compared to blood raised the possibility of a primary CNS non-Hodgkin's lymphoma, which was subsequently confirmed on brain biopsy. EBV DNA quantification acted as a diagnostic marker that led to a change in the management of our patient.
