Radiologic Studies

Aside from laboratory results, including complete blood count, comprehensive metabolic panel, blood gases, and cultures from the wound and blood, radiologic studies may be helpful. As suggested earlier, gas pockets from anaerobic bacterial respiration may be visible on plain film X-ray, ultrasound, CT scan, or MRI. Findings on unenhanced radiograph may consist of soft-tissue edema and subcutaneous emphysema. Ultrasound offers additional evidence, demonstrating hyperechoic foci as well as thickening and gas within the scrotal wall. A CT scan may provide further information, indicating the extent of the soft tissue gas as well as identifying the site of origin. Potential sites could include perianal abscess, incarcerated hernia, or fistulous tract (Uppot, Levy, & Patel, 2003). MRI may be used to better define soft-tissue pathology in some cases of necrotizing fasciitis, but it is not yet recommended as the radiologic study of choice for the diagnosis of Fournier's gangrene (Malangoni & McHenry, 2002; Thomsen & Legome, 2005).
