Bedside ultrasound of the right leg cellulitis showing hyperechoic fat lobules separated by hypoechoic fluid-filled areas, typically known as "cobblestone" appearance.

2024年12月8日 · Ultrasound. Ultrasound is usually the first investigation to evaluate a clinical suspicion of cellulitis. Normally the subcutaneous tissue is hypoechoic with few hyperechoic strands (representing connective tissue). Above this, there is a narrow, relatively hyperechoic epidermal-dermal layer. Muscular fascia lies deep to the subcutaneous layer.

2021年12月14日 · Cobblestoning (having a cobblestone appearance) can occur in a number of hollow organs with mucosa, most commonly the bowel, in the setting of Crohn disease. Longitudinal and circumferential fissures and ulcers separate islands of mucosa, giving it an appearance reminiscent of cobblestones.

Ultrasound of the lower extremity can be used to assess for deep venous thrombosis (DVT), lymphadenopathy, and visualization of subcutaneous edema for evaluation of cellulitis versus...

2005年2月1日 · Ultrasound appearances range from diffuse swelling and increased echogenicity of the skin and subcutaneous tissues (Figure 1, Figure 2 (a)), to a variable cobblestone appearance depending on the amount of perifascial fluid, the degree of subcutaneous oedema and the orientation of the interlobular fat septa. These grey-scale appearances are not ...

2022年9月22日 · In cellulitis, we will see the following ultrasound findings: Figure 3: B-mode image shows cobblestone pattern. Subcutaneous adipose tissue appears hyperechoic with edema between fat lobules. The tissue architecture is maintained. No evidence of abscess is seen. Findings are consistent with cellulitis.

Ultrasound appearances range from diffuse swelling and increased echogenicity of the skin and subcu-taneous tissues (Figs. 1 and 2(a)), to a variable cobblestone appearance depending on the amount of perifascial fluid, the degree of subcutaneous oedema and the orientation of the interlobular fat septa.

2016年9月12日 · As fluid snakes around fat within the hypodermic space it gives the appearance of a cobblestoned street on ultrasound. Figures 2 and 3 demonstrate “cobblestoning”. Compare this image to the thin, homogenous hypodermic layer in figure 1 and you will appreciate how easy it is to identify cellulitis.

2015年10月21日 · On ultrasound, the lower abdomen showed cobblestone-like appearance of the subcutaneous tissue due to soft-tissue edema. This is a non-specific finding often seen on ultrasound of cellulitis. -Joseph Kim, MS4

2016年8月18日 · The echogenicity of the subcutaneous tissue is diffusely increased, and often is traversed by a lattice of broad hypoechoic bands, giving rise to a cobblestone appearance (Figs. 20.3, 20.4 and 20.6). Differentiating interconnected bands of edema fluid from an irregular pus collection can be difficult ( Figs. 20.5 and 20.6 ).
