AbstractWe present the case of a 2-month-old adopted female seeking evaluation in the pediatric emergency department due to a one-day history of decreased right arm movement and fussiness. The physical exam was largely unremarkable with the exception of decreased spontaneous movement of the right upper extremity, obvious discomfort with passive movement and subtle edema of the forearm. Because of concern for non-accidental trauma, plain films were obtained which revealed no signs of traumatic injury. Subsequently, a broader investigation ensued with infectious etiologies in mind. Laboratory evaluation demonstrated anemia, transaminitis, and elevated inflammatory markers. These abnormalities led to the consideration of congenitally acquired infections, specifically syphilis, and serologies were confirmatory. Ultimately, the infant was diagnosed with Pseudoparalysis of Parrot - a rare musculoskeletal manifestation secondary to painful syphilitic periostitis. As Emergency Medicine physicians, it is important to be aware of the growing burden of syphilis infection and reacquaint ourselves with its numerous presentations in the young infant.Copyright © 2021 Elsevier Inc.
