title: Intracranial hematopoiesis in a patient with AIDS-related central nervous system lymphoma and severe pancytopenia.
abstract: The case here reported reflects the difficulty in diagnosing meningeal extramedullary hematopoiesis (EMH), which clinically appeared concomitantly with primary cerebral lymphoma and occurred in a patient with HIV infection and severe pancytopenia. Pancytopenia secondary to HIV infection could be hypothesized as a predisposing factor for the ectopic development of hematopoietic tissue outside the bone marrow. Although rare, intracranial EMH should always be considered in the differential diagnosis of headache and other endocranial hypertension symptoms in patients with chronic bone marrow dysfunction.
