The patient was followed conservatively for 12 years with cross-sectional imaging. The patient was initially diagnosed with an acute left ICA dissection, with significant luminal narrowing. Follow-up imaging revealed the dissection was not completely healed, and a small pseudoaneurysm, about 4\u2009mm in size, was formed in the distal left cervical ICA. During the 12-year observation period, the patient\u2019s pseudoaneurysm expanded from 4.0 mm to 9.0 mm, and the patient presented with ptosis, anisocoria and myosis. Flow diverter embolisation resulted in a radiographic cure of the pseudoaneurysm and resolution of Horner\u2019s syndrome.<\/jats:p>","DOI":"10.1136\/bcr-2020-241156","type":"journal-article","created":{"date-parts":[[2021,5,10]],"date-time":"2021-05-10T13:21:38Z","timestamp":1620652898000},"page":"e241156","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Use
