目的探讨胎儿心脏横纹肌瘤的超声特点及病理特征。方法对2例产前超声诊断心脏横纹肌瘤的引产死胎进行尸解,观察大体及镜下形态,分析其特,最。结果 2例死胎产前超声发现心室腔内或心室壁强回声实质性占位,尸解见心室腔内或心室壁椭圆形界清、实性、淡红色肿物,镜下由典型“蜘蛛样”横纹肌细胞构成;其中1例合并结节性硬化症。结论产前超声检查对胎儿心脏横纹肌瘤的诊断有一定价值,超声诊断胎儿心脏横纹肌瘤需仔细检查脑及肾脏等器官,排除合并结节性硬化症的可能,病理尸解可确诊。
Objective To investigate the ultrasound features and pathological features of fetal cardiac rhabdomyoma. Methods Two prenatal ultrasound diagnosis of cardiac rhabdomyoma induced abortion fetus autopsy, observed in general and microscopic morphology, analysis of its special and most. Results Two cases of stillbirth prenatal ultrasound found in the ventricular cavity or ventricular wall strong echo substantial place, the autopsy see the ventricular cavity or ventricular wall oval-shaped clear, solid, pink tumor, microscopic by the typical “spider Like ”striated muscle cells; 1 case of tuberous sclerosis. Conclusion Prenatal echocardiography has some value in the diagnosis of fetal rhabdomyosarcoma. Ultrasound diagnosis of rhabdomyosarcoma of the fetus needs careful examination of organs such as the brain and kidney to exclude the possibility of tuberous sclerosis. The autopsy may be confirmed by pathology.
