title: [Imagery of human immunodeficiency virus (HIV) encephalitis].
abstract: The authors present the different aspects of HIV encephalitis in CT and MR in a series of 15 patients with anatomopathological proof. Atrophy was the most commonly found lesion (12 patients) and could rapidly be evolutive. White matter lesions (9 patients) were more of ten nodular than diffuse. They were better demonstrated by MRI and did not enhance after intra-venous injection of DOTA-gadolinium. A frequent association with opportunistic infections (toxoplasmosis: 10 patients, CMV:2 patients), lymphoma (4 patients), or PML (3 patients) was observed which emphasized the low specificity of brain imaging in patients with HIV encephalitis.
