In the present vignette, we describe a lateral medullary infarction developed immediately after strenuous straining owing to constipation in a 42-year-old female. There was a dissection in left vertebral artery V4 segment. Computed tomography (CT) angiography revealed beaded appearance of cervical V2 and V3 segments of bilateral vertebral arteries. A follow-up CT angiogram performed about 3 months later showed resolution of vasoconstriction and normalization of vertebral arteries. Reversible cerebral vasoconstriction syndrome (RCVS) is usually known as an intracranial pathologic condition. Extracranial RCVS is very rare. Therefore, the diagnosis of RCVS could be challenging when its location is extracranial, particularly when comingling vertebral artery dissection (VAD) is present because of their similar vascular luminal morphology. Physician should be vigilant about the possibility of a concomitant presence of RCVS and VAD, even in extracranial vessels.
