Blunt internal carotid artery (ICA) injury is rare but undiagnosed can have disastrous clinical consequences.Aim
To report a late presentation of blunt ICA injury in a young male following a road traffic accident.Result
A 16-year-old male presented 11 days following a head injury with a unilateral Horner's syndrome. Imaging confirmed a pseudoaneurysm of the ICA. The patient was treated with anticoagulant therapy.Conclusion
Diagnosis of ICA injury requires a high index of suspicion and presentation with unusual neurological signs following blunt trauma to the head and neck requires prompt investigation.
