Consider cervical artery dissection as the source of stroke in patients younger than age 40.
About 20% of such strokes are due to carotid artery or vertebral artery dissections.
Of these, internal carotid artery dissections are the most common.
These patients often present with a triad of neck and head pain, Horner's syndrome, and pulsatile tinnitus.
MRI/MRA is the best non-invasive diagnostic modality for arterial dissection. Angiography may needed for confirmation.
