Overview

Primary CNS lymphoma is a primary intracranial tumor usually present in those with severe immunosuppression --- commonly in those with AIDS --- and represents around 20% of all cases of lymphomas in HIV infection (other types being Burkitt's lymphoma and immunoblastic lymphoma).

Other Diagnostics Studies

Because imaging techniques cannot distinguish the two conditions with certainty, patients usually undergo brain biopsy if the lesion is solitary or a trial of toxoplasmosis therapy is non-therapeutic. In the future, it may be possible to use PCR assay of cerebrospinal fluid for EBV DNA.
