Methods In this retrospective study, all 12 cases which were diagnosed with suspected prenatal CC,4M over the period in the hospital were analyzed. Information on diagnosis time, types and progression of the lesions during pregnancy, the additional abnormalities, and the outcome of pregnancies were recorded.Results The positive rate of ultrasonic detection of CCAM was about 1.01‰ （1/11 124） before 28 gestation weeks. There were 1 case of type Ⅰ （8%）, 2 cases of type Ⅱ （17%） and 9 cases of type Ⅲ （75%）. Nine pregnancies were terminated and 2 cases were confirmed by pathology. Three neonates were alive and without any symptom now. Conclusions Type Ⅲ is the major type. Ultrasound examination during 20-28 weeks and following up, prenatal consultation, chromosome examination offetus, delivery with a pediatrician standing by, and all suspected neonates being investigated are recommended.展开更多
