In 2004, a 28-year old male presented with a traumatic dissecting pseudoaneurysm of the distal left cervical internal carotid artery was followed conservatively for 12 years with cross-sectional imaging. The patient was originally diagnosed with an acute left internal carotid artery (ICA) dissection, with significant luminal narrowing. Follow-up imaging revealed the dissection was not completely healed and a small pseudoaneurysm, about 4mm in size, was formed in the distal left cervical ICA. During the twelve-year observation period, the patient’s pseudoaneurysm expanded from 4.0mm to 9.0mm and the patient presented with ptosis, aniscoria, and myosis. Flow diverter embolization resulted in radiographic cure of the pseudoaneurysm and resolution of the Horner’s syndrome.
