Arch Otolaryngol Head Neck Surg. 2005;131(5):454-456. doi:10.1001/archotol.131.5.454

Financial Disclosure: None.

In the postantibiotic era, pseudoaneurysm (PA) of the internal carotid artery (ICA) is a rare but potentially lethal complication of parapharyngeal or retropharyngeal infections. We report a case of a PA of the ICA that was caused by parapharyngeal infection and provide a review of the literature.

A 4½-year-old girl presented with a 3-week history of fevers, neck pain and stiffness, headache, and a rash over her lower extremities. Lyme disease titers (IgM and IgG) were obtained by her primary care provider and found to be abnormal, and amoxicillin therapy was initiated. A few days later, her parents observed that her right eyelid was drooping and her pupils were unequal. She also had dysphagia and hoarseness. She was admitted to a community hospital for further evaluation and treatment and subsequently transferred to the Children’s National Medical Center, Washington, DC.
