Detection of intracapsular rupture of silicone breast prostheses using MR imaging is often performed by identifying the "linguine sign" [1]. The linguine sign is easily differentiated from simple radial folds that are seen in intact implants. However, more subtle signs of intracapsular rupture, including undulating subcapsular lines and the "teardrop sign," are less often recognized [2-5] and may prove difficult for the less experienced radiologist to differentiate from complex radial folds of intact implants. In this essay, we illustrate the MR imaging findings of complex radial folds in intact implants and compare them with findings of incomplete shell collapse in ruptured implants in a surgically confirmed series of explanted silicone breast prostheses.
使用磁共振成像（MR）检测硅凝胶乳房假体的囊内破裂通常是通过识别“细面条征”来进行的[1]。细面条征很容易与完整植入物中所见的简单放射状褶皱区分开来。然而，囊内破裂的更细微征象，包括起伏的囊下线和“泪滴征”，则较少被识别[2 - 5]，对于经验较少的放射科医生来说，可能难以将它们与完整植入物的复杂放射状褶皱区分开来。在本文中，我们展示了完整植入物中复杂放射状褶皱的MR成像表现，并将其与手术证实的一系列取出的硅凝胶乳房假体中破裂植入物的不完全外壳塌陷表现进行比较。
