Vignette A 60-year-old man presented with vertigo, dysarthria and left weakness. MRI showed multifocal infarctions of posterior circulation (Figure A). He suffered from subarachnoid hemorrhage (SAH) on the 10th day (Figure, D) and died on the 30th day. © 2013 American Academy of Neurology Zhang, et al.

Imaging Zhang, et al. © 2013 American Academy of Neurology Figure. Radiologic Imaging Features of the Patient. A. Diffusion-weighted imaging showed acute infarctions of cerebellar hemispheres and pons. B. CT angiography showed vertebrobasilar dolichoectasia. C. High-resolution MRI (T1-CUBE) showed a crescentic high signal of the basilar artery and left vertebral artery, indicating intramural hematoma of artery dissection. D. CT showed subarachnoid hemorrhage in the suprasellar cistern. © 2013 American Academy of Neurology Zhang, et al.

Vertebrobasilar Dolichoectasia with Dissection Manifested as Infarct and Subarachnoid Hemorrhage His CT angiography showed vertebrobasilar dolichoectasia (VBD) (Figure B). High-resolution MRI showed dissection of basilar artery and left vertebral artery (Figure, C). VBD with dissection can manifest as sequential infarct and SAH, which predicts poor prognosis1. High-resolution MRI is a useful tool to detect dissection in VBD. No consensus has been reached on treatment of VBD; antiplatelet agents, anticoagulants, surgical and endovascular treatment are all treatment options2. References 1.
