目的探讨产前超声诊断胎儿肝脏肿瘤的价值。方法对孝感医院于2005年6月-2011年11月确诊为肝脏肿瘤的8例胎儿进行回顾性分析,运用产科系统超声检查方法详细检查每例胎儿,对肝脏肿瘤的大小、部位、形态、内部回声及血流分布进行观察,并进行追踪随访。结果 8例胎儿肝脏肿瘤均为单发。其中肝脏海绵状血管瘤6例,肝母细胞瘤2例,均经引产后病理证实或产后手术证实。8例肝脏肿瘤边界均较清晰,形态较规则,6例肝脏海绵状血管瘤中,3例位于肝右叶,3例位于肝左叶;5例为低回声团,1例为不均高回声团;4例血流信号较丰富,2例见少许血流信号。2例肝母细胞瘤均位于肝右叶,血流信号均较丰富,1例为实性低回声,另1例为不均高回声。8例胎儿肝脏肿瘤产前均未能明确定性。结论胎儿肝脏肿瘤超声表现较复杂,产前超声较易检出胎儿肝脏肿瘤,但不易鉴别肿瘤性质。
Objective To investigate the value of prenatal ultrasound in the diagnosis of fetal liver tumors. Methods Retrospective analysis was performed on 8 fetuses diagnosed as liver tumors from June 2005 to November 2011 in Xiaogan Hospital. The fetuses were examined in detail by the method of obstetric system ultrasound. The size, location, morphology, Echo and blood flow were observed and followed up. Results 8 cases of fetal liver tumors were single. Including liver cavernous hemangioma in 6 cases, hepatoblastoma in 2 cases, both confirmed by pathology or postpartum surgery confirmed by induced labor. Of the 8 cases, the border of hepatic tumor was clear and the morphology was relatively regular. Among the 6 cases of hepatic cavernous hemangiomas, 3 were located in the right lobe of the liver, 3 were located in the left lobe of the liver, 5 were hypoechoic masses and 1 was hypoechoic ; 4 cases of blood flow signal is more abundant, 2 cases see a little blood flow signal. 2 cases of hepatoblastoma were located in the right lobe of the liver, the blood flow signals are more abundant, 1 case of solid hypoechoic, and the other 1 case of uneven high echo. 8 cases of fetal liver tumors prenatal were not clear qualitative. Conclusion Fetal liver tumors are more complicated by ultrasound. Prenatal ultrasound is easier to detect fetal liver tumors, but it is not easy to identify the nature of the tumor.
