Imaging findings of breast silicone implant rupture are well described in the literature. On MRI, the linguine sign indicates intracapsular rupture, while the presence of silicone particles outside the fibrous capsule indicates extracapsular rupture. The linguine sign is described as the thin, wavy hypodense wall of the implant within the hyperintense silicone on T2-weighted images indicative of rupture of the implant within the naturally formed fibrous capsule. Hyperintense T2 signal outside of the fibrous capsule is indicative of an extracapsular rupture with silicone granuloma formation. We present a rare case of a patient with a silicone calf implant rupture and discuss the MRI findings associated with this condition.
乳房硅胶植入物破裂的影像学表现已在文献中得到充分描述。在MRI上，“通心粉征”提示囊内破裂，而纤维囊外存在硅胶颗粒则提示囊外破裂。“通心粉征”被描述为在T2加权图像上，植入物内高强度硅胶内的薄而波浪状的低密度壁，提示植入物在自然形成的纤维囊内破裂。纤维囊外的高强度T2信号提示伴有硅胶肉芽肿形成的囊外破裂。我们报告一例罕见的硅胶小腿植入物破裂患者，并讨论与此病症相关的MRI表现。
