To evaluate the perfusion magnetic resonance (MR) imaging characteristics of cerebral toxoplasmosis and lymphoma in patients with acquired immunodeficiency syndrome (AIDS). ⋯ Reduced rCBV i toxoplasmosis lesions is probably due to a lack of vasculature within the abscess; increased rCBV in lymphomas is probably due to hypervascularity in foci of active tumor growth; and decreased rCBV in the edema is probably due to vasoconstriction associated with increased interstitial pressure. Perfusion MR imaging is a rapid, noninvasive tool that may allow differentiation between cerebral lymphoma and toxoplasmosis in patients with AIDS.
