胎儿脉络丛囊肿(choroid plexus cyst,CPC)是指声像图上脉络丛内边界清晰的无回声区。一般是单侧、单个出现,也可以双侧出现或者一侧有多个囊肿。脉络丛位于侧脑室、第三脑室和第四脑室,超声能显示的脉络丛主要位于侧脑室内。1984年Chudleigh等~([1])首次报道了超声检查中观察到胎儿CPC。随后的20多年内,大量的这方面的研究和文章认为CPC与胎儿的染色体异常有关,尤以三倍体综合征为主,对于是否需行侵入性的染色体核型分析存在争议。那么,
Fetal choroid plexus cyst (choroid plexus cyst, CPC) refers to a clear anechoic area within the choroid plexus on the sonography. Generally unilateral, single appear, can also appear on both sides or more than one cyst on one side. Choroid plexus located in the lateral ventricle, the third ventricle and the fourth ventricle, ultrasound can show the choroid plexus located mainly in the lateral ventricle. In 1984 Chudleigh et al. ([1]) first reported that fetal CPC was observed during sonography. Subsequent more than 20 years, a large number of studies and articles in this area that CPC and fetal chromosomal abnormalities, especially in triploid syndrome, the need for invasive chromosomal karyotype analysis is controversial.
