Abstract

Our objective is to describe the clinical entity and MR imaging appearance of fat necrosis after trauma, a benign cause of palpable soft-tissue lesions in children. A related objective is to establish MR imaging criteria that can be used reliably to differentiate this entity from other more serious causes of soft-tissue masses. Fat necrosis after trauma is a common cause of palpable lumps in children and has a benign course on long-term follow-up. When characteristic MR imaging findings are seen, conservative therapy is appropriate.
