Abstract:
Objective To summarize imaging appearances of brain in AIDS patients,as to supply the evidences of imaging diagnosis for this disease . Methods CT or/and MRI appearances of brain in 19 patients with AIDS of nervous system type were reviewed . Results 3 cases showed the symmetry signal abnormal in bilateral whiter matter and 2 cases showed brain atrophy in 5 patients with HIV encephalitis.2 cases of toxoplasma encephalitis appeared multiple abnormal density or/and signal intensity in the brain and multiple ring enhancement . 3 patients with lymphoma displayed single or multiple nodule in the brain and nodular-enhancement or inhomogenous enhancement.3 patients with brain infarction displayed lower density in the basal ganglia on CT.2 patients with progressive multifocal leukoencephalopathy displaied multiple patch abnormal signal intensity of the white matter in frontal and parietal lobus.1 patient with cryptococcal infection showed abnormal signal and ring enhancement of the pons.1 patient with cryptococcal meningitis and 2 patients with intracranial hypertension had not abnormal imaging appearances.Conclusion Most lesions of the brain in AIDS patient may be detected by CT and MRI,but the definite diagnosis is still in need of combining with clinical appearances and other relative examination.
