case_images: (A,B) 3D time-of-flight magnetic resonance angiography (TOF-MRA) revealed a dilated, tortuous, and elongated vertebral artery and basilar artery (arrow). (C) The contrast-enhanced MRI revealed a significant expansion of the basilar artery (arrow).

case_images: Magnetic resonance imaging (MRI) and MRA demonstrated a VBD compressing the right ventrolateral region of brainstem and the trigeminal nerve root entry zone (REZ) (Figures 1A,B). The contrast-enhanced MRI revealed a significant expansion of the basilar artery (Figure 1C) and the widest part of the basilar artery was about 12-mm-diameter.
case_images: Digital subtraction angiography (DSA) examination identified a basilar artery dissection indicating the delayed image of distal basilar artery and the stratification and retention of contrast agent (arrow).
