A four-year-old girl was referred to our service to investigate a mass in her left forearm. About a year before she had cellulitis in the same place which was treated and resolved with antibiotics. A month previous to our consult she notices a soft tissue swelling in her left forearm and a pediatrician referred her to an oncologist for investigation. On physical examination, she presented with a medial bulging in her left forearm with local pain and no inflammatory signs. There was no history of fever. The plain radiograph showed a lytic lesion oriented along the axis of the ulna surrounded by fading sclerosis. In the Computed Tomography there was a lytic lesion with periosteal new bone formation. The diagnosis was Brodie’s abscess which is a form of subacute osteomyelitis. It is a collection of purulent material surrounded by granulation tissue and reparative sclerotic bone.
