Rupture of the extracranial carotid artery caused by misdiagnosed infected pseudoaneurysm during deep cervical abscess drainage: A case report

Infected aneurysms or pseudoaneurysms of the extracranial carotid artery are extremely rare, but they can lead to lethal complications. In some cases, infected pseudoaneurysms can be masked by the excessive inflammation of surrounding tissues. Here we describe the case of a 69-year-old woman with several comorbidities, who presented with a rapidly enlarging left neck bulge. CT was suggestive of an abscess involving the left common carotid artery. Colour Doppler ultrasound did not document intralesional flow.
