摘 要:目的 探讨浆细胞性乳腺炎(plasma cell mastitis,PCM)的超声及钼靶X线特征,以及两者联合应用在诊断中的应用价值。资料与方法回顾性分析经病理证实的29例(31个)PCM的超声及钼靶X线表现,均为非妊娠或非哺乳期妇女,中位年龄35岁(18~64岁)。结果 彩色多普勒超声表现可分为4型:单纯导管扩张型(5/31)、囊性型(8/31)、低回声实质型(16/31)、囊实混合型(2/31)。16个低回声实质型病灶内血流信号为0~Ⅰ级8个,Ⅱ级4个,Ⅲ级4个,频谱特点为低速低阻型(10/11)。钼靶X线表现可分为4型:炎性样型(5/31)、导管扩张型(4/31)、局限浸润型(16/31)、结节肿块型(6/31)。单纯应用超声检查的阳性诊断符合率为52%,单纯应用X线钼靶检查的阳性诊断符合率为32%,两者无统计学差异(P〉0.05)。超声与X线钼靶联合应用的阳性诊断符合率为77%,与单纯行超声和X线钼靶检查比较,两者有统计学差异(P〈0.05)。结论 超声与X线钼靶的联合应用能明显提高PCM的阳性诊断符合率。Objective To investigate the ultrasonography and mammography features of the plasma cell mastitis,and to evaluate the value of ultrasonography and mammography in diagnosis of plasma cell mastitis.Materials and Meth-ods Twenty-nine patients(31 lesions)with histologically confirmed plasma cell mastitis,aged from 18 to 64 years(mean age 35 years),were examined with ultrasonography and X-ray mammography.The imaging features were retrospectively reviewed.Results Based on the ultrasonography features,the plasma cell mastitis were classified into four types:duct ectasia type(n=5),cystic type(n=8),hypoechoic type(n=16)and cystic-solid type(n=2).The grades of color sign in the 16 lesions of hypoechoic type were as follows:grade 0-I in 8,grade II in 4,grade III in 4 lesions.The characters of the Doppler spectrums were low-velocity and low-resistance.The mammography types were as follows:inflammation-like type(n=5),duct ectasia type(n=4),focal infiltration type(n=16)and nodular type(n=6).The positive diagnostic rate of ultrasonography and mammography were 52% and 32% respectively.The positive diagnostic rate of ultrasonography combined with mammography was 77%,compared with ultrasonography or mammography,there was significant difference(P0.05).Conclusion Combination of ultrasonography and mammography can improve the positive diagnostic rate of the plasma cell mastitis.
