Teaching NeuroImages: HIV-associated cerebral vasculopathy with multiple nodular aneurysms

HIV-associated cerebral vasculopathy with multiple aneurysms has been widely reported in children1 and has to be considered in HIV-infected patients with high CSF viral load, but only few cases in adults have been published so far. Nodular and fusiform aneurysms (figure, A–D) are a typical imaging finding2 that may lead to suspicion of an autoimmune etiology by mimicking polyarteritis nodosa. These aneurysms might carry clinical significance with regard to the risk of subarachnoid or intracerebral hemorrhage, or causing infarction through formation of emboli. Highly active antiretroviral therapy leads to remission of these pathologic vessel alterations2 (figure, E and F).
