Diagnosis: Pseudoaneurysm of the left internal carotid artery due to infection
The computed tomographic scan revealed that there were extensive soft tissue swelling and lymphadenopathy extending from the left parapharyngeal region to the root of the neck, but no clearly defined abscess. Of note, there was a significant narrowing of the left internal carotid artery as it passed through the inflammatory tissue, with a focal dilatation (Figure 1 and Figure 2).
