Lemierre's Syndrome Complicated by Common Carotid Artery Pseudoaneurysm with Sentinel Bleed - A Case Report.

Rationale and patient concerns: A 50-year-old female admitted with right neck swelling and fever was initially diagnosed with infective cervical lymphadenopathy accompanied by internal jugular vein thrombosis for which broad-spectrum antibiotics and anticoagulants were started.

Diagnosis and treatment: A few days later, she developed right common carotid pseudoaneurysm with sentinel bleed which was further managed by common carotid artery repair with the help of pericardial allograft by cardiothoracic vascular surgery and ear, nose and throat team.

Outcome and take-away lessons: This report emphasises the need of having a high index of suspicion for Lemierre's syndrome and its unusual presentation, as well as a multidisciplinary approach to addressing both venous and arterial complications associated with this entity and achieving outstanding results.
