A case study of Carotid Artery Skull base dissection - US Clues suggesting distal pathology
Mathew Christie, Salford Royal Foundation NHS Trust
51 Years old patient admitted with left sided weakness and numbness and headache. MR brain scan performed: right hemisphere multiple infarcts.
A carotid ultrasound then requested which demonstrated bilateral internal carotid artery (ICA) luminal filling but very low velocities compared to the common carotid arteries (CCAs) ? significance. Additional imaging was therefore suggested.
A carotid MR demonstrated bilateral ICA abnormal luminal narrowing centred at the junction with the skull base with mural haematoma consistent with bilateral ICA dissection.
