Abstract:Objective: To explore the characteristics of MRI of fetal abdominal cystic lesions, and to provide reference for its differential diagnosis and treatment. Methods: One hundred and two cases of fetal abdominal cystic lesions cases whose gestational weeks was 15~37W from January 2009 to September 2018 in our hospital were collected, and the results of fetal MRI examination were analyzed and compared with the result confirmed by postpartum follow-up. Results: Among 102 cases of fetal abdominal cystic lesions, 37 cases were located in the lower abdomen. Ovarian cysts(24 cases, 64.9%) are the most common cases. There were 16 cases in the right upper abdomen, and choledochal cysts(6 cases, 37.5%) are the most common cases. There were 9 cases of left upper abdomen, and multiple digestive tract cyst(6 cases, 55.6%) are the most common cases. There were 40 cases of retroperitoneal lesions, mainly cystic lesions from urinary system, lymphatic malformations and adrenal hematoma. Conclusion: The localization of fetal abdominal cystic lesions has certain rules, and comprehensive analysis combined with other MRI imaging signs and ultrasonic characteristics can improve the diagnostic level and reduce misdiagnosis.
