聚丙烯酰胺水凝胶注射隆乳术后MRI诊断价值

目的　探讨聚丙烯酰胺水凝胶注射隆乳术后不良反应的MRI表现及其临床价值。方法　 16例聚丙烯酰胺水凝胶注射隆乳者行乳腺MRI平扫 ,MR表现与临床症状对照。结果　MRI显示 16例中 :① 2例 (4只 )注入物所形成的“假体”基本正常 ;② 1例于哺乳期发生一侧乳房巨大积乳囊肿 ;③ 3例 (6只 )双侧乳房不对称 ,双侧注射部位不一致 ;④ 10例 (2 0只 )注入物所形成的“假体”不完整。 16例MRI表现与临床表现相符 ,6例行手术取出注射物 ,手术所见与MRI相符。结论　乳腺MRI对聚丙烯酰胺水凝胶隆乳术后并发症有较大的诊断价值。

Applications of magnetic resonance imaging in diagnosis of the complications after breast augmentation with polyacrylamide hydrogel injection

OBJECTIVE: To explore the clinical value of magnetic resonance (MR) imaging in the diagnosis of the complications after breast augmentation with polyacrylamide hydrogel injection. METHODS: MRI was performed in 16 patients who had breast augmentation with polyacrylamide hydrogel injection. The results of magnetic resonance imaging were compared with the clinical symptoms. RESULTS: MRI examinations of the 16 patients showed that (1) 4 breasts in 2 patients were comparatively natural; (2) a large lacteal cyst was detected in one patients in lactation; (3) breast asymmetry occurred in 3 patients (6 sides); (4) in 10 patients (20 sides), the injected gel was in irregular form. The results of MRI were in accord with the clinical symptoms. CONCLUSION: MRI is of great diagnostic value for the complications after breast augmentation with polyacrylamide hydrogel injection.
