History of right buttock soft tissue injury. Surrounding induration. Evaluate for abscess. Targeted grayscale and color Doppler evaluation of the region of erythema and induration demonstrates a small hypoechoic focus measuring 1.1 x 0.4 x 1.0 cm which appears slightly decreased in size from the prior. No significant surrounding inflammatory changes. Shadowing is noted from the adjacent packed wound.
Probable 1.1 cm complex poorly loculated fluid collection within the subcutaneous soft tissues is too small to drain.
