目的 提高浸润性小叶癌不同X线征象 ,尤其是易忽视征象的认识。方法 回顾性分析 2 7例 (2 8个病灶 )浸润性小叶癌的X线征象 ,并与临床资料、B超检查对照。结果 ①浸润性小叶癌X线表现为肿块 13个 ,肿块伴钙化 5个 ,结构扭曲 4个 ,不定性钙化 2个 ,单纯恶性钙化、局灶性不对称致密各 1个 ,阴性 2例。② 18个肿块改变为主者 ,以不规则形生长 (5/ 18)伴浸润性或星芒状边缘最常见 (15/ 18)。③ 2 8个病灶中以易忽视征象表现的 7个 ,其中结构扭曲 4个、不定性钙化 2个、局灶性不对称致密 1个。④本组检出病变敏感性 :X线 86% (2 4/ 2 8) ,临床检查 64% (18/ 2 8) ,B超 85% (17/ 2 0 ) ,三者结合 ,敏感性提高至 96% (2 7/ 2 8)。结论 浸润性小叶癌以浸润性边缘或星芒状边缘的不规则肿块结构扭曲等改变最常见。X线、B超和临床检查三者结合 ,能提高肿瘤的检出率。
Objective To improve the different X-ray signs of invasive lobular carcinoma, especially the easily overlooked signs. Methods The X-ray signs of infiltrating lobular carcinoma in 27 cases (28 lesions) were retrospectively analyzed and compared with clinical data and B-ultrasound. Results ① The X-ray findings of infiltrating lobular carcinoma were 13 tumors, 5 lesions with calcification, 4 structures distorted, 2 calcifications of calcification, 1 malignant calcification, 1 focal asymmetric densification and 2 negative findings. ② The 18 lumps were changed to the main ones, with irregular growth (5/18) with infiltrative or stellate edges most commonly (15/18). ③ There were 7 lesions in 2 8 lesions that were easily disregarded. Among them, 4 were distorted in structure, 2 were calcified in uncertainty, 1 in focal asymmetry. The group detected the sensitivity of the lesions: 86% (24/28) of X-ray, 64% (18/28) of clinical examination and 85% (B / 85%) of B- To 96% (2 7/2 8). Conclusion Invasive lobular carcinoma with infiltrative or stellate edges of the irregular shape of the irregularity of the tumor changes the most common changes. X-ray, B ultrasound and clinical examination of the combination of the three can improve the detection rate of tumors.
