摘　　要：目的总结多发性对称性脂肪增生病的影像学表现。方法回顾分析12例多发性对称性脂肪增生病的 CT 和 MRI 表现。结果异常增多的脂肪组织主要沉积于颈前和项部皮下组织、胸锁乳突肌和斜方肌深面、颈后三角、颌下腺和腮腺周围,也见于锁骨上窝、围绕脊柱旁肌肉、咽后间隙、喉等部位,导致颈部诸结构受压。病变脂肪组织的密度和信号与正常脂肪组织的密度和信号相同。结论 CT 和 MRI 能准确反映增厚脂肪的分布范围及其对周围器官组织的压迫情况,并能排除软组织肿瘤。Objective To investigate the CT and MRI manifestations of Madelung disease. Methods The CT and MRI manifestations of 12 cases of Madelung disease were analyzed retrospectively. Results The CT and MRI manifestations：cross-sectional CT showed that abnormally proliferated fat mainly deposited in anterior or posterior subcutaneous tissues of the neck, deep into the sternomastoid and trapozius muscles, situated in posterior cervical triangle, around the salivary glands, and excess fat was also found to be situated in supraclavicular fossa, around the paraspinal muscles and larynx, and so on. The abnormally proliferated fat can compress surrounding organs and tissues. The density of the abnormally proliferated fat was equal to that of normal fat. The MRI manifestations：the distributin of the thickened fat was equal to that seen with CT. The signal intensity of the thickened fat was equal to that of normal fat. Conclusions CT and MRI can accurately show distribution of the thickened fat, compression of surrounding organs and tissues and exclude soft tissue tumors. MRI seemed to be superior to CT.
