IVY sign in early infarction

History of 3hrs left side weakness. 

Axial FLAIR images of brain show abnormal serpigenous high signal along right cerebral convexity in peri sylvian region, normally not visualized due to flow voids represents cortical branches of right MCA with an abnormal very sluggish flow -"IVY" sign can be the early and only sign of acute ischemia. 
Brain parenchyma in the involved territory show normal signals.

Also reported in Vasculitis :  Post Tb Meningitis Vasculitis induced infarcts with "IVY" sign

Initially described in MOYA-MOYA.

FVH is unique in that it does not represent thrombus, but
rather sluggish or disordered blood flow through vessels AJNR

Although the most frequent location is
within the Sylvian fissure, FVH has been noted within distal
branches of the anterior, middle, and posterior cerebral arteries, as well as more proximally within the intracranial carotid
artery and the proximal MCA AJNR
