Vascular complications related to multiple hereditary exostoses are uncommon. We present a 39-year-old
male patient with multiple exostoses in the upper and lower limbs with an associated positive familial history of such lesions. He experienced a sudden onset of left-side ataxia and hypoesthesia secondary to a left
lateral medullary infarction, which was due to a stenotic-pattern vertebral artery dissection (V1-V4). This
complication is very rare as a differential diagnosis in the vertebro-basilar dissection spectrum, and a nonspecific relation has been found.
