Lower-limb lymphoscintigraphy did not differentiate lipedema from non-lipedemic overweight/obesity matched by leg volume: abnormal scans (83% vs 96.8%), dermal backflow (5.9% vs 9.7%), absent inguinal nodes (0% in both), and mean lymphoscintigraphy score (1.686 vs 2.323) showed no statistically significant differences.

Evidence over time

Lymphoscintigraphic alterations in lower limbs in women with lipedema in comparison to women with overweight/obesity — Chachaj et al. (2023) ✓ verified — conflicting · cross sectional · 2023 · reading confidence: high
“Score linfocintilográfico médio: 1,686 ± 1,304 (lipedema) vs 2,323 ± 1,222 (obesidade) — sem diferença estatística (p=NS)”
Cross-sectional comparison directly tests whether lymphoscintigraphy can differentiate lipedema from obesity; finds no significant differences in any scintigraphic parameter, contradicting the diagnostic differentiation hypothesis for this
