摘要: 该文报道了1例经手术病理证实的乳腺巨大恶性叶状肿瘤患者。患者女，58岁，CT平扫表现为左侧乳腺巨大类圆形高密度影肿块影，边界清楚。MRI平扫表现为T1WI肿瘤呈等、稍低及高混杂信号，T2WI抑脂序列边缘呈高信号，局部呈低信号；扩散加权成像肿瘤边缘呈高信号，CT增强肿瘤实性部分呈不均匀强化，MRI增强肿瘤呈花环样不均匀强化，多个感兴趣区(ROI)动态时间信号曲线(TICmax)呈流出型(III型)及平台型(II型)，肿瘤内见多发增粗血管分支进入。术后病理证实为恶性叶状肿瘤。
Abstract: This paper reports a case of huge malignant phyllodes tumor of breast confirmed by surgery and pathology. The patient is a 58-year-old female. On plain CT scan, she showed a huge round-like high-density shadow mass on the left breast with clear boundary. On MRI plain scan, the tumor showed equal, slightly low and high mixed signal on T1WI, high signal on the edge of lipid-inhibiting sequence on T2WI, and low signal locally. Diffusion-weighted imaging showed high signal intensity on tumor edge, heterogeneous enhancement on CT-enhanced tumor solid part, garland-like heterogeneous enhancement on MRI-enhanced tumor, outflow-type (type III) and plateau-type (type II) dynamic time signal curves of multiple regions of interest (ROI), and multiple thickened vascular branches entered the tumor. Postoperative pathology confirmed that it was a malignant phyllodes tumor.
