Ultrasound for the Evaluation of Skin and Soft Tissue Infections

Skin and sott tissue infections, including abscesses and cellulitides, are common problems seen by physicians. The treatment of soft tissue infections varies depending on the depth of infection or the presence of a fluid collection requiring incision and drainage. Ultrasound is a valuable tool in the evaluation of skin and soft tissue infections, enhancing our ability to diagnose an abscess cavity or deeper infection and has been shown to be more reliable than clinical exam alone. The judicious use of ultrasound allows for more appropriate patient care and management of their underlying infection. It can prevent an unnecessary procedure or identify occult abscesses that may go on to develop a more severe infection requiring hospitalization. In this article,we discuss the utility of ultrasound as a diagnostic tool for skin and soft tissue infections, techniques to optimize scanning, and the potential drawbacks of its use.
