Carotid artery dissection (CAD) is a haemorrhage into the arterial wall disrupting the intimal layers of the vessel. We present a case of a 16-year-old male with a non-traumatic spontaneous CAD. The patient presented with Horner's syndrome following an episode of orbital cellulitis secondary to sinusitis requiring sinus drainage surgery. Subsequent magnetic resonance imaging (MRI) revealed a CAD. The patient was treated with antiplatelet medication.
Keywords: horner's syndrome; non-traumatic carotid artery dissection; orbital cellulitis; sinusitis.
