title: Pineal toxoplasmosis mimicking pineal tumor in an AIDS patient.
abstract: A pineal mass in a patient with acquired immunodeficiency syndrome (AIDS) is reported. Computed tomography (CT) scan revealed a nodular mass in the pineal region with foci of calcification and obstruction of the aqueduct mimicking a pineal tumor. At autopsy, the brain revealed a well-circumscribed lesion with central necrosis in the pineal region suggestive of toxoplasma and involving the periaqueductal area. Susceptibility of a patient with AIDS to opportunistic infections should be considered.
