طفل عمره ٤ سنوات بعد نزلة برد، صار يعرج ويشتكي ألماً خفيفاً في الورك، وحرارته ٣٧٫٤، ويمشي. التحاليل طبيعية. ما الأرجح؟

A 4-year-old after a cold starts limping with mild hip pain, T 37.4 °C, and is walking. Bloods are normal. What is most likely?

1. Leukaemia
2. Transient synovitis
3. Pelvic fracture
4. Septic arthritis

Answer: B) Transient synovitis. Transient hip synovitis can follow a viral illness; the child is well, with low-grade fever and walking, and improves with rest and NSAIDs. Septic arthritis is excluded if high fever or refusal to bear weight occur.
