Learning objectives To identify and characterize different types of abdominopelvic cysts on fetal MRI To present an illustrated guide introducing the most common and also the rare lesions that can appear as an abdominopelvic cyst in the fetus To revise the role and the technique of fetal MRI in cases of abdominopelvic cysts
Read more Background Abdominopelvic cysts are reported as a relatively frequent ultrasound finding during pregnancy. Cysts diagnosed in the first trimester are usually rare, most cysts are detected in the second- and third-trimester. First- and second-trimester cysts are more likely to be associated with other abnormalities with a higher probability of an adverse perinatal outcome, such as fetal or neonatal loss, neonatal complications, and the need for surgical treatment. Cysts recognized in the third trimester are usually isolated lesions, generally resulting in better...
Read more Findings and procedure details Abdominopelvic cysts encompass a broad spectrum of neoplasms and malformations that are usually classified according to fetal gender, gestational age at the time of the diagnosis, and anatomic location. The most common pathologies arise from the urinary tract, the ovaries, the gastrointestinal tract, the liver, and the mesentery. The rare causes of fetal cysts are: adrenal cysts, splenic cysts, pancreatic cysts, choledochal cysts, and umbilical vein „cysts” (varices).  Hepatic cysts:  This malformation is rare, usually unilocular. They could be intra- or...
Read more Conclusion Fetal abdominopelvic cysts can originate from many structures and have a broad differential diagnosis. When a cystic abdominal lesion is detected for the first time it should undergo a detailed ultrasound exam and then a fetal MRI is helpful in characterizing the etiology. This poster provides an illustrated guide that may help radiologists specify the ultrasound finding of an abdominopelvic cyst.
