To investigate the significance and images characters of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts(FTB).
From June 2005 to June 2012, 13 cases with 96 fat necrosis lumps after FTB, were retrospectively reviewed. The pre-operative images of ultrasound and mammography, as well as the post-operative histologic results were collected.
All the 96 lumps were histologically diagnosed as fat necrosis. They were lipo-necrotic cysts with thin wall(29 lumps), or thick wall(52 lumps), or no wall(15 lumps). The cysts with wall could be distinguished both in the images of ultrasound and mammography, but the cysts without wall could only be found in mammography images, not in ultrasound images.
Most fat necrosis lesions show a special cystic images with thin or thick wall in ultrasound and mammography. Irregular lesions without wall can be distinguished in the mammography images, but may be mis-diagnosed in the images of ultrasound. The images characters of fat necrosis lesions in mammography are not confused with the breast tumor.
探讨超声及乳腺钼靶在诊断乳房脂肪移植术后脂肪坏死（FTB）中的意义及影像特征。
回顾性分析2005年6月至2012年6月期间13例乳房脂肪移植术后出现96个脂肪坏死肿块的患者资料。收集术前超声及乳腺钼靶影像资料以及术后组织学检查结果。
96个肿块经组织学诊断均为脂肪坏死。其中薄壁脂肪坏死性囊肿29个，厚壁脂肪坏死性囊肿52个，无壁脂肪坏死性囊肿15个。有壁囊肿在超声及乳腺钼靶影像中均可鉴别，而无壁囊肿仅在乳腺钼靶影像中可发现，超声影像中未发现。
多数脂肪坏死病灶在超声及乳腺钼靶检查中表现为具有薄壁或厚壁的特殊囊性影像。无壁的不规则病灶在乳腺钼靶影像中可鉴别，但在超声影像中可能误诊。乳腺钼靶检查中脂肪坏死病灶的影像特征与乳腺肿瘤不易混淆。
