目的分析乳腺叶状肿瘤(PTs)的MRI特征,提高PTs与纤维腺瘤(FAs)的鉴别诊断水平。方法搜集经手术病理证实、行MRI检查的PTs患者10例及FAs患者33例,分析其MRI表现,并进行统计学分析,比较两者的差异。结果 10例PTs中,术后病理诊断良性2例,交界性8例。叶状肿瘤具有短期内明显增大病史,在最大横径、深分叶、T1WI上存在高信号区域、T2囊性成分、低信号的分隔、不均匀强化、增多的血管、时间-信号强度曲线上,与FAs有统计学差异(P=0.026)。在T2WI信号、胆碱(Cho)峰值上,两者没有统计学差异。结论 PTs和FAs在MRI表现上有一定差异,有助于PTs的正确诊断。
Objective To analyze the MRI features of breast tumor (PTs) and to improve the differential diagnosis between PTs and fibroadenoma (FAs). Methods Totally 10 patients with PTs and 33 patients with FAs who had been confirmed by surgery and pathology were analyzed. The MRI findings were analyzed and compared statistically. Results Of the 10 cases of PTs, 2 cases were pathologically diagnosed and 8 cases were borderline. The phyllodes tumor had a significantly increased history in the short term. There was a high signal area on T1WI in the largest transverse diameter, deep lobe, cystic components of T2, segregation of low signal, uneven enhancement, increased blood vessel, time-signal intensity curve There was a statistically significant difference with FAs (P = 0.026). There was no statistical difference between T2WI signal and Cho peak. Conclusion PTs and FAs have some differences in MRI findings, which is helpful for the correct diagnosis of PTs.
