Which feature is typical of transient synovitis?

• A. High fever and leukocytosis
• B. Abnormal radiographs
• C. Well-appearing child, afebrile, normal inflammatory markers, self-limited (<1 week)
• D. Requires antibiotic therapy

Answer: (C)

Transient synovitis presents as a benign, self-limited hip problem in a child who looks well. The hallmark is a normal, non-toxic exam with no fever and normal inflammatory markers (white count, ESR, CRP), and symptoms that improve within a short time, typically less than a week. This contrasts with septic arthritis, where fever, ill appearance, elevated inflammatory markers, and a need for urgent antibiotics or drainage are common. Imaging may be normal in transient synovitis, and the absence of systemic symptoms plus quick resolution fits this diagnosis.
