Wheel within a wheel sign (diagram)

Case contributed by Brian Gilcrease-Garcia
Diagnosis not applicable

This is one of several appearances of a lesion caused by hepatic candidiasis on ultrasound. The outer hypoechoic "wheel" corresponds to fibrosis, which surrounds a middle hyperechoic "wheel" of inflammation. The central hypoechoic focus represents an area of central necrosis.

Of note, this appearance is not reported by CT imaging.
