Giant External Carotid Aneurysm: A Rare Cause of Dyspnoea, Dysphagia and Horner's Syndrome

We report a case of life-threatening giant external carotid artery (ECA) aneurysm. The 89-year-old patient presented with severe dyspnoea and dysphagia with Horner's syndrome and cluster headache. Surgical repair with ECA ligation and reconstruction of the internal carotid artery using a prosthetic PTFE graft was successfully performed. The compressive symptoms promptly resolved in the early post-operative period.
