Near-infrared fluorescence lymphatic imaging (NIRF-LI) of 20 individuals with Stage I-II lipedema showed dilated lymphatic vessels (94-100% of legs), increased lymphatic propulsion rate (1.4 events/min vs 0.9 in controls, p=0.0102/0.0258), and complete ABSENCE of dermal backflow, in contrast to lymphedema; foot fat-sparing attenuation was seen in ~81% of legs, and absence of dermal backflow correctly excluded lymphedema in a previously misdiagnosed patient.

“AUSÊNCIA DE DERMAL BACKFLOW nas pernas em todos os 20 indivíduos com lipedema (estágios I-II), em contraste marcante com linfedema”
Pilot imaging study directly addressing whether functional lymphatic imaging differentiates lipedema from lymphedema, finding distinct features (no dermal backflow, increased propulsion, foot fat-sparing) that distinguish early lipedema; th [grade capped moderate->low per curated Oxford N4]
Context (PECO)
Answers these questions
- Is lipedema a distinct disease, separate from obesity and lymphedema? consistent
- Can MRI, lymphoscintigraphy, or DXA differentiate lipedema from lymphedema and other fat distributions? consistent
- Can lymphoscintigraphy differentiate lipedema from lymphedema? consistent
