To describe the sonographic and mammographic features of patients whose breasts have been injected with silicone.
Between July 1997 and August 1999, 14 patients with a history of breast injection of liquid silicone underwent physical, mammographic, and sonographic examination. Mammographic findings were classified as macronodular, micronodular, or mixed striated patterns. Sonographic appearances were classified as macronodular, micronodular, mixed, or snowstorm patterns.
Eighty-six percent of the patients had abnormal physical examination. Well-defined nodules were palpable in 4 patients, 6 patients had diffusely heterogeneous breasts on palpation, and 2 patients had a combination of heterogeneous texture with dominant nodules. Sonographic examination revealed the presence of marked echogenicity (i.e., snowstorm pattern) in all 14 patients; in 11 patients it was associated with macronodules and/or micronodules, whereas in 3 patients only snowstorm appearance was noted. Mammographic patterns were macronodular in 7 patients and mixed macronodular and micronodular in 6 patients.
Both mammography and sonography can help identify free silicone injected directly into the breast.
描述乳房注射过硅酮的患者的超声和乳腺X线摄影特征。
1997年7月至1999年8月期间，14例有乳房注射液态硅酮病史的患者接受了体格检查、乳腺X线摄影和超声检查。乳腺X线摄影结果分为大结节型、小结节型或混合条纹型。超声表现分为大结节型、小结节型、混合型或暴风雪型。
86%的患者体格检查异常。4例可触及边界清晰的结节，6例触诊时乳房弥漫性不均匀，2例质地不均匀并伴有优势结节。超声检查显示所有14例患者均有明显的回声增强（即暴风雪型）；11例与大结节和/或小结节有关，而3例仅表现为暴风雪样外观。乳腺X线摄影模式中，7例为大结节型，6例为大结节和小结节混合型。
乳腺X线摄影和超声检查均有助于识别直接注入乳房的游离硅酮。
