Osteomyelitis can mimic which of the following tumor?

Distinguishing between hematogenous osteomyelitis and a bone sarcoma is difficult when there is no trauma, no systemic disease, and no sign of infection locally, radiographic changes of soft tissue swelling, coical tunneling, focal cancellous bone lysis, focal coical resorption, and a periosteal reaction in osteomyelitis are often mistaken for tumors, and Ewing sarcoma is usually associated with fever.(Refer: Nelson's Textbook of Pediatrics, SAE, 1st edition, pg no. 2471)
