She has developed the left neck swelling over the course of the past month. She is initially evaluated with lateral neck ultrasonography as an outpatient; this demonstrates enlarged cervical lymph nodes without fluid collection or abscess. She completes a course of clindamycin for presumed cervical lymphadenitis and is subsequently treated with a course of amoxicillin–clavulanic acid after the first course of antibiotic agents fails to improve her symptoms. Parents state that they have not appreciated a significant change in the degree of neck swelling after the 2 antibiotic drug therapy courses, and the girl endorses a major increase in neck pain and headache last night that is unresponsive to acetaminophen or ibuprofen, both of which had previously been alleviating her pain. She is also noted to have pupillary asymmetry for the previous 2 days.\n\nShe has not had fevers, vomiting, seizures, weight loss, or changes in speech or vision. She remains at her neurologic baseline. There is no history of trauma or recent surgery. She is fully immunized and has no known allergies.\n\nIn the emergency department she is well-appearing, afebrile, and with age-appropriate vital signs. She is noted to have partial left-sided ptosis and miosis, as well as tender, palpable left-sided cervical lymphadenopathy (Fig 1).\n\n\n\nFigure 1. \nLeft-sided ptosis and miosis.\n\n\n\nThis girl s clinical presentation is consistent with Horner syndrome, also known as oculosympathetic palsy, which is caused …
