title: Colour Doppler imaging of an ascending pharyngeal artery arising from the internal carotid artery.
abstract: We present two cases of an extracranial collateral of the internal carotid artery. The descriptions include Doppler recording and colour flow-mapping. The report underlines the epidemiological, embryological and anatomic features (including Doppler characteristics) of the variant, with a view to helping sonographers whenever the carotid examination proves difficult.
