Multidisciplinary diagnostic dilemma in differentiating Madelung’s disease — the value of superb microvascular imaging technique: A case report

Figure 2 Ultrasound images of tumor masses in the area of the parotid gland. A: Grayscale ultrasound showing typical superficial lipoma well-circumscribed with parallel linear and thin echogenic lines; B: Power Doppler showing several small internal dots minimal flow/vascularity; C: Superb microvascular imaging confirming low vascularity (several unrelated dots), which is a weak suspicious for liposarcoma.
