Abstract
OBJECTIVE. The goal of our study was to report on the prevalence and the neuroradiologic manifestations of cerebrovascular complications in children infected with HIV. We also elucidate the types of vascular involvement, identify their anatomic distribution, and discuss possible causes.MATERIALS AND METHODS. We conducted a retrospective study of 567 patients (age range, 1 month-29 years; median age, 5.47 years) who acquired HIV as children. Of these, 426 patients (75%) were evaluated with neuroimaging studies. We reviewed these studies to identify the cerebrovascular abnormalities and classify them by type, anatomic location, and shape.RESULTS. Eleven children (2.6%) were found to have cerebrovascular lesions. Only one had focal neurologic symptoms at the time of diagnosis. Twenty-six aneurysms were found in seven patients, and 27 infarctions were found in eight patients. In four of the patients with infarctions, fusiform aneurysms of the cerebral arteries were also identified. Most patients had advanced ...
