Toxoplasmosis of the central nervous system (CNS) is the most common cause of intracerebral lesions in patients with AIDS. It is now standard clinical practice to treat empirically, based on clinical and radiographic findings, and to perform a biopsy of the lesion only in those patients who fail to have a clinical and radiographic response after two weeks of therapy. This study describes the presentation and response to therapy of central nervous system toxoplasmosis in patients with AIDS at a private practice in Mexico City. ⋯ The probability of surviving 6 months after the diagnosis of toxoplasmosis was 60%. The findings of these authors are similar to those reported in other series where toxoplasmosis of the CNS is a late complication of HIV infection associated with a CD4+ cell count of < 100 cells/microL. However, survival was short in spite of a good response to therapy.
