Lipoblastoma: 1-year-old girl with a right wrist mass. Directed ultrasound (a) of the right wrist portrays a well-circumscribed, predominately hyperechoic lesion in the superficial soft tissues. Coronal (b) and sagittal (c) T1W pre-contrast images show a predominately fat-signal lesion centered around the distal flexor carpi radialis tendon with internal low signal intensity components. T1W FS post-gadolinium (d) images demonstrates enhancement of the internal curvilinear components due to the dense capillary network of the myxoid stroma.
