A 34 year-old man developed transient vertigo associated with left neck pain.
Magnetic resonance angiogram: (Left) intracranial; (Middle) left neck; (Right) right neck. Note the normal caliber of the right vertebral and basilar arteries. However, the left vertebral is very small intracranially and poorly seen in the neck. This picture could result from a congenital hypoplastic vertebral or from a dissection and a subsequent "string sign".
