I need to answer this exam-style question regarding a 10-year-old with pain and a mass in the right lumbar region. There's no fever, but pain increases on extension, suggesting psoas irritation or possibly a psoas abscess. Changes in the spine hint at spinal TB causing this abscess. No fever aligns with a cold abscess, and the hip's flexed position relieves pain. Pyonephrosis would have different symptoms. So I'll conclude that the most probable diagnosis is a psoas abscess.
