摘要
目的探讨乳腺分叶状肿瘤的X线钼钯及MR表现。方法搜集我院经病理证实的乳腺分叶状肿瘤病人18例,常规行双乳轴位及内外侧斜位钼靶摄片,4例加做MR平扫加增强扫描。分析其X线及MR表现,以提高诊断准确率。结果 18例病人均行钼靶摄影,4例行MR摄影,表现为肿块16例(其中1例为复发),结构紊乱2例(均为复发)。单发肿块12例,多发4例。18例中良性5例,交界性8例,恶性5例。肿块形态呈分叶状11例、圆形3例,类圆形2例。16例中肿块周围有晕环14例,边缘模糊2例,2例伴腋下淋巴结肿大,1例伴沙砾样钙化。1例MR于T2WI高信号内见低信号分隔,增强后其内可见囊变区,为其特征性表现。结论乳腺分叶状肿瘤发病率低,生物学行为复杂,而影像学表现缺乏特异性,分析并认识其影像学特征对术前诊断很重要。
Objective To explore the imaging features of molybdenum target X-ray and MR for mammary phyllodes tumor.Methods Mammary X-ray image data of 18 patients confirmed with mammary phyllodes tumor by surgical pathology were received conventional and mediolateral oblique mammography.Four of them had MR enhancement scanning simultaneously.The X-ray and MR features were analyzed to improve the diagnostic accuracy.Results All 18 cases underwent molybdenum target X-ray and 4 cases underwent MR,there were 16 cases with palpable mass in clinic（1 case of recurrence）,and 2 cases with structural disorder（2 cases of recurrence）.There were 12 cases with single mass and 4 cases with multiple mass;18 patients with mammary phyllodes tumor,5 of which were benign,8 were borderline and 5 were malignant.There were 3 round lumps and 2 oval and 11 phyllodes.Among 16 lumps,14 lumps were with clear edges,of which 2 were with obscure edges.2 cases combined with axillary lymph nodes enlargement and 1 case with grit calcification.Low signal showed in T2WI high signal in 1 case,the cystic change after signal enhanced was its characteristics.Conclusion While the incidence of breast phyllodes tumor was low,biological behavior was complex and X-ray images have no specificity.It is very important for preoperative diagnosis to analyze its imaging features.
