A 16-year-old Korean boy presented with acute onset vertigo, dysphagia and gait ataxia of 16 hours duration. He had history of headache and neck pain along with transient vertigo during a water slide ride 12 days before presentation. CT brain showed left cerebellar and left lateral medullary infarcts. CT angiography showed left vertebral dissection with occlusion of left posterior inferior cerebellar artery. A 52-year-old Indian man, presented with acute onset global aphasia and right hemiparesis within 3 hours of onset of symptoms. He received intravenous tissue plasminogen activator (tPA) with partial improvement in his symptoms. He had headache and neck pain since 2 weeks, ever since he had a water slide ride. CT brain was normal, while the CT angiogram showed left carotid dissection. Cervical artery dissection has been reported with roller coaster rides and rarely with delayed presentations. Delayed presentation of cervical artery dissection after water rides have not been reported.
