[Tomodensitometric aspects of a case of intracranial toxoplasmosis in an immunosuppressed patient].

The case of a 42 years old man who had a monoblastic acute leukemia treated by a bone-marrow graft is described. The patient died of a cerebral toxoplasmosis and a cerebral computed tomography done two days before is correlated with anatomopathologic slices done in the same planes than the computed tomagraphy examination. There is a good correlation between necrotic abceded areas and hypodense areas accompanied by serpiginous fixations of contrast media. The immunocompromised patient is very favorable for the development of a cerebral toxoplasmosis. CT, while not specific, has the advantage to suspect the diagnosis which must be discussed with other oportunistic infections, leukemic infiltrates, methotrexate encephalopathy, progressive multifocal encephalopathy, and small infarcts.
