乳腺叶状囊肉瘤是一种少见的乳腺肿瘤,占全部乳腺肿瘤的0.2%～2.5%,是双向分化的纤维上皮肿瘤[1]。临床上常被误诊为乳腺纤维瘤而行局部肿瘤切除术,术后极易复发,因此诊断和治疗常较困难。本文收集经手术病理证实,彩色多普勒超声、X线及其他影像学方法和病理资料完整的乳腺叶状囊肉瘤16例,结合影像征象进行回顾性分析,以探讨其影像特征,旨在提高诊断水平。 Breast cystosarcoma is a rare breast tumor, accounting for 0.2% to 2.5% of all breast tumors, is a bi-directional differentiation of fibroepithelial tumors [1]. Clinically often misdiagnosed as breast fibroids and local tumor resection, easy to relapse after surgery, so the diagnosis and treatment is often more difficult. In this paper, 16 cases of cystosarcoma of the breast, which is proved by operation and pathology, complete with color Doppler ultrasound, X-ray and other imaging methods and pathological data, are retrospectively analyzed with the imaging signs to explore the features of the images and aim to improve Diagnostic level.
