目的　探讨注射聚丙烯酰胺水凝胶隆胸术后的临床及X线表现。方法　 12例 2 4只乳房均有明确注射聚丙烯酰胺水凝胶隆胸史 ,均经临床检查及X线摄片。结果　 1只乳房坚硬如石 ,2只分别较对侧质韧 ,13只可触及质硬结节。X线片上填充物与腺体呈等密度 14只 ,高密度 8只 ,稍低密度 2只。填充物全部或大部分位于腺体后。与腺体分辨不清 14只。填充物主体内见多发结节 12只 ,主体外见多发结节 13只 ,结节呈等或高密度。结论　聚丙烯酰胺隆胸术后部分会出现变硬及硬结现象 ,X线片上填充物与腺体分辨不清时影响乳房病变的观察 Objective To investigate the clinical and radiological manifestations of polyacrylamide hydrogel after breast augmentation. Methods Twelve cases of 24 breasts had a clear history of polyacrylamide hydrogel breast augmentation. They were clinically examined and X-ray. Results A hard breast as stone, 2 were more tough than the contralateral, 13 can reach hard nodules. X-ray films on the packing and gland was 14 equal density, high-density 8, slightly lower density 2. All or most of the filler is behind the gland. And the glands indefinable 14 only. See multiple nodules in the body of the main body of 12, see multiple nodules outside the main body of 13, nodules were equal or high density. Conclusion Polyacrylamide breast augmentation surgery will appear part of the hardening and induration, X-ray film on the glands and gland unclear affect the observation of breast lesions
