DOI: 10.1016/j.wneu.2017.03.089
Abstract: BACKGROUND Cerebral hyperperfusion sometimes occurs after removal of chronic subdural hematoma (CSH) and usually resolves within a few days without any symptoms. Subcortical low intensity (SCLI) on fluid-attenuated inversion recovery (FLAIR) magnetic resonance images is… read more here.

DOI: 10.1016/j.wneu.2020.05.069
Abstract: BACKGROUND Hyperperfusion in the posterior circulation is a rare complication after surgical revascularization for vertebrobasilar (VB) steno-occlusive diseases. We report a case of symptomatic cerebellar hyperperfusion after superficial temporal artery (STA)-superior cerebellar artery (SCA) bypass… read more here.
