Follow-up multi-modal MRI scans. (a) DWI showing acute ischemic infarction in the left mesencephalon-pontine junction (red arrow). (b) DWI showing old infarction with reactive gliosis (red arrow). (c) TOF-MRA demonstrating an abnormal BA caliber (red arrow), bifurcation at the third ventricle floor, and bilateral vertebral arteries are present with enlarged diameters (blue arrow). (d-g) PWI showing decreased cerebral blood volume (CBV) and cerebral blood flow (CBF) of the medulla oblongata, pons, and cerebellum, and elongated MTT and TTP of the right cerebellum. (h) DWI showing acute ischemic infarction in the right medulla oblongata (red arrow) and cerebellum (blue arrow). (i) DWI showing acute ischemic infarction in the right pons with Wallerian degeneration (red arrow). (j) TOF-MRA showing an enlarged diameter and increased length of the BA (red arrow), bifurcation at the level of the bilateral ventricles, and non-observable right vertebral artery (blue arrow). (k-n) PWI shows decreased CBV and CBF of the bilateral medulla oblongata, and cerebellum, and elongated TTP of the right medulla oblongata. (o) High-resolution MRI showing signs of a double lumen of the BA (red arrow). (p) Basi-parallel anatomic scanning showing a larger diameter of the BA than that seen with TOF-MRA (red arrow) and an observable right vertebral artery (blue arrow)
