目的 :探讨胎盘囊肿的声像图特征 ,为临床诊治提供客观依据。方法 :本组 15例 ,孕龄 2 8～ 4 1周 ,使用 Apogee- CX型彩超仪 ,探头频率 3.5 MHz,常规对胎儿、胎盘及羊水情况进行观察。结果 :在胎盘子面均见向外突出的囊性肿物 ,单发 11例 ,多发 4例。超声诊断均与临床、病理诊断相符。结论 :超声诊断胎盘囊肿可为临床诊治及鉴别诊断提供客观依据 Objective: To explore the characteristics of placenta cyst sonography, to provide an objective basis for clinical diagnosis and treatment. Methods: 15 cases of this group, gestational age 2 8 ~ 4 1 week, the use of Apogee-CX-type color Doppler, the probe frequency of 3.5 MHz, routine observation of fetal, placental and amniotic fluid. Results: In the placenta surface are seen protruding outward cystic mass, single in 11 cases, multiple in 4 cases. Ultrasound diagnosis is consistent with clinical and pathological diagnosis. Conclusion: Ultrasound diagnosis of placental cysts can provide objective evidence for clinical diagnosis and differential diagnosis
