Cerebral toxoplasmosis occurs mainly in immunocompromised hosts as a reactivation of latent Toxoplasma gondii infection. In the diagnostic process, magnetic resonance imaging (MRI), serum testing, and biopsy are used. We describe a case of a 43-year-old HIV-positive patient presenting with altered levels of consciousness, aphasia, and hemiparesis. The patient had a history of antiretroviral therapy discontinuation for about 3 years. MRI revealed lesions, suggesting cerebral toxoplasmosis and subacute hemorrhage, serum tests for Toxoplasma gondii were positive. Antiparasitics and glycocorticosteroids were administered. A decline in viral load and clinical improvement were observed, however CD4+ T-cell count continued to decrease. The patient’s state worsened, he developed CMV and bacterial pneumonia, which led to his death. What is crucial in the management of an HIV-infected patient is effective and continuous antiretroviral therapy. Discontinuation of the treatment may result in AIDS and lead to poor recovery of the CD4+ T-cell population, even after reimplementation of antiretroviral therapy and a decrease in viral load.
