Objective To investigate the ultrasonographic features of partial hydatidiform mole to establish a proper diagnosis. Methods Retrospective analysis was conducted on the history, pathological results and ultrasonographic features of 35 cases diagnosed as partial hydatidiform mole (29 cases diagnosed by ultrasound examination and 6 cases by histopathology) from January 2013 to December 2014 in the First Affiliated Hospital of Xi’ an Jiaotong University. Results Among 29 cases diagnosed as partial hydatidiform mole by ultrasound examination, 25 cases were confirmed by histopathology, and the diagnosis coincidence rate was 86. 2% (25/29). There were 4 cases misdiagnosed, including missed abortion in 2 cases, incomplete abortion in 1 case and myoma degeneration in 1 case. Among 6 cases diagnosed as partial hydatidiform mole by histopathology but missed diagnosed by ultrasound examination, there were 3 cases of missed abortion by ultrasound diagnosis, 1 case of incomplete abortion, 1 case of myoma degeneration, and 1 case of complete hydatidiform mole. Conclusion Ultrasonography combined with history can diagnose the majority of partial hydatidiform mole, but the untypical cases usually need combining pathology with laboratory examination for diagnosis.%目的：探讨部分性葡萄胎的声像图特点,以提高部分性葡萄胎的诊断符合率。方法回顾性分析西安交通大学医学院第一附属医院2013年1月至2014年12月35例部分性葡萄胎患者(超声诊断29例,病理诊断6例)的病史、病理结果及超声声像图。结果29例超声诊断为部分性葡萄胎的患者,与病理结果相符合的有25例,其诊断符合率为86.2%(25/29)；误诊病例4例,其中稽留流产2例,不全流产1例,肌瘤变性1例。6例病理诊断为部分性葡萄胎而超声漏诊的患者中,有3例超声诊断为稽留流产,1例诊断为不全流产,1例诊断为肌瘤变性,1例诊断为完全性葡萄胎。结论超声检查结合病史能够诊断绝大多数的部分性葡萄胎,但不典型的患者往往需结合病理以及实验室检查进行诊断。
