Chorioangiomas are relatively frequent, benign and highly vasculated tumours of the placenta. In a few rare cases they show an excessive growth. Placental necrosis, preterm delivery and foetal asphyxia are well-known complications. Another severe complication is maternal thrombocytopenia, leading to serious thrombopathia. In cases with unfavourable examination conditions, it may be difficult to distinguish ultrasonographically between a chorioangioma and foetal elements. In our case, final diagnosis of a 10 by 9 cm chorioangioma became possible by the use of Doppler ultrasound. Arterial and venous signals were seen all over the tumour. During the following period of observation, the tumour did not grow and pregnancy was uneventful. Diagnosis of chorioangiomas should be made as early as possible to enable the obstetrician to adjust the management of pregnancy to complications that can be expected.
绒毛膜血管瘤是胎盘相对常见的良性且血管高度丰富的肿瘤。在少数罕见情况下，它们会过度生长。胎盘坏死、早产和胎儿窒息是众所周知的并发症。另一种严重并发症是母体血小板减少症，可导致严重的血栓形成异常。在检查条件不佳的情况下，通过超声检查可能难以区分绒毛膜血管瘤和胎儿成分。在我们的病例中，通过使用多普勒超声最终诊断出一个10×9厘米的绒毛膜血管瘤。在肿瘤各处均可见动脉和静脉信号。在接下来的观察期内，肿瘤没有生长，妊娠过程顺利。绒毛膜血管瘤的诊断应尽早做出，以便产科医生能够根据预期的并发症调整妊娠管理。
