Although point of care ultrasound has many applications, our principal use for soft tissue ultrasound is evaluation for abscess. Â Point of care ultrasound can differentiate cellulitis from abscess and has been shown to change management.
- Is there a hypoechoic collection?
- Is there cobblestoning consistent cellulitis?
1. Transverse and Longitudinal views of area of concern
Cellulitis is a diffuse inflammatory process and the resultant hypoechoic edema results in the typical “cobblestoning” seen on ultrasound.
When abscess forms in the setting of cellulitis, both cobblestoning and a defined collection of fluid may be seen on ultrasound. Â This fluid is typically hypoechoic or anechoic but debris may be seen within the abscess cavity as well.
