Materials and Methods: Conventional ultrasonography (US) and real-time freehand
US elastography were performed in nine patients (M:F = 4:5; mean age, 53
years; 29-64 years) with soft-tissue lipoma confirmed by surgical resection. The elastogram
was color-coded by 256 scales according to the degree of strain induced by
light compression. The relative strains for lipoma and surrounding soft tissue were
measured and mean strains were examined by using a Wilcoxon signed rank test.
Results: The elastograms showed red to sky-blue color in all lipomas and predominantly
black in surrounding soft tissue. The mean relative strain (±standard deviation)
was 67.9±28.5, 77.1±25.3, 63.3±31.2, and 15.7±18.3 for total, intramuscular, and
subcutaneous lipoma, and surrounding soft tissue, respectively. The mean strain of
the lipoma was significantly higher than one of surrounding soft tissue (p = .008,
Wilcoxon signed rank test).
Conclusion: Real-time elastography yields characteristic elastographic features of
soft tissue lipoma distinguishing from those of adjacent soft tissues.
