Primary CNS Vasculitis DSA

A 35 yo male with basal ganglionic infarcts.
Cerebral Angiogram; Right ICA injection (oblique view) showing irregularities involving right ICA cavernous supra clinoid portion and ACA A1 segment; Multiple dilatations and focal narrowings giving "beaded" appearance suggestive of Primary CNS Vasculitis / Arteritis - appears to be HIV associated as meanwhile patient found to be TRIDOT Positive.
HIV’s CNS complications result either from direct HIV infection or as a consequence of opportunistic infections.
HIV related CNS vasculitis is a direct neurological complication of HIV, where intracranial vessels develop aneurysmal dilatations and is associated with either infarction or bleeding.
