Sonographic Detection of Necrotizing Fasciitis

Necrotizing fasciitis is a rare, life-threatening, flesh-eating bacterial infection that quickly destroys soft tissue beneath the skin. Left untreated, it can result in the loss of limbs or even death. A diagnosis is most often made through laboratory tests and diagnostic imaging such as magnetic resonance imaging, computed tomography (CT), and sonography. This case study demonstrates the use of sonography to assist in the detection and characterization of necrotizing fasciitis. In this case, CT provided the necessary diagnostic information to accurately diagnose necrotizing fasciitis. The prompt diagnosis for this patient facilitated expedited treatment in an effort to stem progressive damage to the affected limb.
