Carotid artery dissection may result in focal weakness and/or sensory loss and amaurosis fugax, and therefore mimic a typical stroke.
There may be a carotid bruit.
Carotid artery dissections can also cause a Horner’s syndrome due to compression of the sympathetic fibres travelling with the internal carotid.
