Abstract
Cervical artery dissection and patent foramen ovale (PFO) are relevant causes of ischemic stroke (IS) in young adults. We report the case of a 35-year-old previously healthy man who presented with severe vertigo, gait ataxia, and bradycardia, later diagnosed with cerebellar infarction secondary to bilateral vertebral artery dissection. Further investigation revealed the presence of a PFO. This case underscores the importance of thorough etiological investigation of IS in young adults, focusing on the identification of cervical artery dissections and structural cardiac abnormalities as risk factors.
