Figure 7: A 50-year-old woman presented with recently worsening headache. Time-resolved (A) and axial (B) CT angiograms show a high-flow right occipital AVM (arrows). Whole brain CT perfusion (C and D) shows high CBF (black arrows in C) and CBV (black arrows in D) in the nidus and low CBF (white arrows in C) and CBV (white arrows in D) in the perinidal area, suggestive of perinidal ischemia. There is no evidence of cerebellar ischemia on the FLAIR (E) and diffusion (F) images. CBF (arrows in G) and CBV (arrows in H) are low in the contralateral cerebellar hemisphere, suggesting crossed cerebellar diaschisis
