High-resolution duplex sonography (11-12 MHz) measuring subcutis+cutis thickness 8 cm above the medial malleolus distinguished lipedema (~16 mm) from non-lipedema (11±2.8 mm) and at the medial knee (25.5 mm vs 14.7±5 mm), with proposed severity grading (12-15 mm mild, 15-20 mm moderate, >20 mm distinct, >30 mm marked) and a homogeneously hyperechogenic 'snow storm' subcutis without echo-free clefts differentiating lipedema from lymphedema.
