Overview
Ultrasound can be used in cases of occult abscesses. It is useful for the aspiration of pus in children, and it helps to reduce hospital stay. It can also help distinguish cellulitis from osteomyelitis. The findings on sonography vary depending on the severity and location of the infection. For more superficial skin and subcutaneous tissue infection, increased echogenicity and diffuse thickening may be seen. In the case of an abscess, the fluid appears as hypoechoic strands between connective tissue and hyperechoic fat. In the presence of perifascial fluid, a distinctive 'cobblestone' appearance is seen. However, these features may also be seen in non-infectious causes of tissue edema and therefore are not pathognomonic for the disease. The identification of hyperemia in the tissue via color Doppler indicates the presence of inflammation which helps distinguish infectious from non-infectious causes of edema.
