目的分析乳腺分叶状肿瘤(PT)的钼靶X线表现,对照病理结果,以期提高对PT的诊断能力。方法回顾性分析2009年8月至2014年11月收治的16例经手术病理证实PT的X线表现及病理特征。结果 16例PT的X线表现均为类圆形、分叶状肿块,8例为肿块伴钙化(其中1例成簇钙化灶),8例边缘光滑,5例见透明晕,5例边缘毛糙,3例呈浸润性改变。良性10例(3例术中快速病理报腺瘤,术后病理报PT,其中1例伴炎性变,2例伴腺病、腺瘤形成),交界性3例,恶性3例(其中1例内含有纤维肉瘤成分,周围伴腺病、腺瘤形成)。结论 PT的钼靶X线表现缺乏典型的特征性,良恶性征象之间存在很大的交叉性,难以鉴别,且还需与巨大纤维腺瘤、少钙化的粘液癌及髓样癌等相鉴别。PT的诊断最终依赖于病理学检查。
Objective To analyze the mammographic X-ray findings of lobulated breast tumor (PT) and to compare the pathological findings with the aim of improving the diagnostic ability of PT. Methods Retrospective analysis of X-ray findings and pathological features of 16 patients with pathologically confirmed PT from August 2009 to November 2014 were retrospectively analyzed. Results The X-ray findings of 16 cases of PT were round and lobulated, 8 cases were mass calcification (including 1 case of calcification), 8 cases were smooth margin, 5 cases were clear halo, 5 cases were rough , 3 cases showed invasive changes. Benign in 10 cases (3 cases of intraoperative rapid pathological adenoma, postoperative pathology reported PT, including 1 case of inflammatory changes, 2 cases with adenosis, adenoma formation), 3 cases of borderline, 3 cases of malignant (1 The cases contain fibrosarcoma components, accompanied by adenosis, adenoma formation). Conclusions PT mammography is characterized by a lack of typical features, there is a great cross between benign and malignant signs, it is difficult to identify, and also with the giant fibroadenoma, mucinous mucinous carcinoma and medullary carcinoma phase identification . The diagnosis of PT ultimately depends on the pathological examination.
