The objective of this study was to describe the sonographic features of deep-seated lipomas. METHODS: A retrospective review of the sonographic features of 64 deep seated lipomas in 64 patients (43 females, 21 males, mean age 46.5, range 16-77 years) seen over an 8-year period (1998-2006) was undertaken. RESULTS: Features evaluated were location, size, shape, marginal definition, internal echogenicity, including the presence of intermingled muscle fibres and linear internal echoes, acoustic transmission and vascularity. Confirmation was histological in 37 (58%) cases and by typical magnetic resonance imaging (MRI) appearance in 27 (42%) cases. CONCLUSION: The results show that although the features of deep-seated lipoma are more variable than those reported for subcutaneous lipomas, the presence of thin internal echoes in conjunction with other less specific features should enable a correct diagnosis.
本研究的目的是描述深部脂肪瘤的超声特征。方法：对在8年期间（1998 - 2006年）就诊的64例患者的64个深部脂肪瘤的超声特征进行回顾性研究（43例女性，21例男性，平均年龄46.5岁，范围16 - 77岁）。结果：评估的特征包括位置、大小、形状、边缘清晰度、内部回声，包括是否存在交织的肌纤维和线性内部回声、声传导及血管情况。37例（58%）经组织学证实，27例（42%）通过典型的磁共振成像（MRI）表现证实。结论：结果表明，尽管深部脂肪瘤的特征比皮下脂肪瘤的特征变化更大，但内部细回声与其他不太特异的特征相结合应能做出正确诊断。
