PEMPix is the American Academy of Pediatrics Section on Emergency Medicine’s annual visual diagnosis competition. This year, in addition to the 10 finalists I will be presenting (virtually) at the National Conference and Exhibition I will be sharing three cases online in advance of the conference. This is the first of the three cases.
This case was submitted by…
An 11-year-old boy presented to the emergency department with left-sided facial swelling. He and his parents noticed this about two weeks ago. He first thought it was a pimple, but it was mobile and nontender. It has since become firmer and continues to enlarge at a relatively rapid pace. He has not had fever or recent illnesses. His past medical history of asthma with a couple of cases of remote sinusitis. Despite the swelling, he has not had any pain when he pushes on the area or when he moves his facial muscles or chews..
On exam he is well appearing and afebrile with normal vital signs. There is a distinct area of prominence over his left maxilla that is firm and nontender. He has normal dentition including no dental caries. His oropharynx is normal. His cranial nerve function and sensation throughout his face is normal.
His labs were notable for a normal CBC with differential, ESR, and CRP.
To better figure out what this swelling was the team obtained a CT scan of his face, and here is a sagittal view.
A. Odontogenic Abscess
B. Dentigerous Cyst
C. Giant Cell Tumor
D. Adenomatoid Odontogenic Tumor
E. Periapical Cyst
