A 9-year-old girl presented to our emergency department with a 6-week history of swelling and pain in the left side of her jaw. She was initially seen in an emergency department at another hospital, where she was treated with clindamycin hydrochloride (Cleocin) and instructed to follow-up with her pediatrician. Three days later, her pediatrician changed her therapy to amoxicillin-clavulanate. Her symptoms slowly regressed over the next 2 weeks. Her mother stated that the swelling had almost completely resolved by then. Three days before admission, her symptoms recurred. She was seen in the same emergency department, where a computed tomographic scan of the head and neck was performed (Figure 1 and Figure 2). She was then transferred to our facility with a presumptive diagnosis of facial abscess.
