摘　　要：目的 探讨聚丙烯酰胺水凝胶（PAHG）注射隆乳术后并发症的MRI特点及其诊断价值.方法 回顾性分析32例PAHG注射隆乳术后患者的临床和MRI资料.结果 32例中,17例（30只）乳腺假体包膜破裂,表现为多发的团块状长T1长T2信号,内可见低信号影分隔 6例（12只）硬结形成,表现为皮下、腺体内或肌间隙内散在的T2WI明亮高信号结节影 2例（4只）乳腺MRI可见假体严重变形、不对称 2例（4只）乳腺伴发无菌性炎症,表现为乳腺腺体结构紊乱,腺体内可见线条样稍长T1长T2信号影,增强扫描未见异常强化灶.MRI表现与临床表现相符.结论 聚丙烯酰胺水凝胶隆乳术后各种并发症的MRI表现有一定特点,乳腺MRI扫描可指导临床诊断和治疗.Objective To investigate the clinical value of MRI in the diagnosis of the complications after breast augmentation with polyacrylamide hydrophilic gel（PAHG） injection. Methods The MR imaging and clinical data of 32 patients who had breast augmentation with polyacrylamide hydrophilic gel injection were retrospectively reviewed. Results In the 32 patients, there were 17 cases （30 breasts） with envelope rupture, which appeared as mass-like long T1 and long T2 signal with hypointense septa; 6 cases （12 breasts） with callosity,the images showed sporadic nodules with high signal on T2 WI; prosthesis asymmetry occurred in 2 cases（4 breasts） ;aseptic inflammation in 2 cases （4 breasts） with pieces of slightly long T1 and long T2 signals,and none abnormal reinforcement was seen after enhancement. MRI findings were corresponded to the clinic manifestations. Conclusion Since each complication after breast augmentation with PAHG has its own MR features, breast imaging plays important role in guiding clinical diagnosis and treatment for the complications after mammoplasty.
