title: Cerebral toxoplasmosis in a patient with acquired immunodeficiency syndrome.
abstract: Cerebral toxoplasmosis commonly affects patients with advanced HIV immunodeficiency. Toxoplasmosis in patients who are immunocompromised can be severe and debilitating in patients with Central Nervous System (CNS) involvement and the condition may be fatal. We report the case of a 40-year-old man who was a known case of HIV and presented with cerebral toxoplasmosis. His Magnetic Resonance Imaging (MRI) scan showed multiple ring enhancing lesions with extensive surrounding oedema in supratentorial as well as infratentorial region. Lesions were mainly located in the periventricular region as well as at the grey-white matter junction and showed enhancement in the periphery as well as a tiny nodular enhancement in the centre. Patient was started on Septran DS, empirically for toxoplasmosis and steroids to reduce intracranial pressure. On follow up MRI scan after 10 days there was a reduction in size, number and enhancement of the masses with decrease in the surrounding oedema. Patient was clinically stable, oriented and his fever settled. He was discharged from hospital on same medication and advised to continue regular follow-up.
