“…The differential diagnosis of a fetal abdominal cyst detected in the second or third trimester includes cystic structures originating from either the gastrointestinal tract (mesenteric, omental, intestinal duplication, hepatic or choledochal cysts) or the genitourinary tract (ovarian, renal, urachal and adrenal cysts). After exclusion of megacystis, the differential diagnosis of an abdominal cyst detected in the first trimester includes cystic structures originating from the gastrointestinal tract as, aside from megacystis, no other cysts originating from the genitourinary tract have been reported in the first trimester.…”

“…With improvements in image resolution, use of the transvaginal route and more detailed assessment of fetal anatomy in the first trimester, structural abnormalities such as abdominal cysts are more frequently visualized. These cysts originate from various structures, but most commonly are renal, bowel, mesenteric, ovarian, hepatic or biliary in origin. It is often difficult to diagnose accurately the nature of the cyst antenatally, therefore it is also difficult to predict its postnatal outcome and decide on a management strategy.…”

“…It is often difficult to diagnose accurately the nature of the cyst antenatally, therefore it is also difficult to predict its postnatal outcome and decide on a management strategy. Moreover, most cases reported in the literature are diagnosed in the second and third trimesters. Reports of cases of fetal abdominal cyst detected in the first trimester are rare; hence their outcome and optimal management have not been well established.…”

“…Fetal abdominal cystic lesions are relatively common and have an incidence of 1/1,000 [ 11 ]. The abnormal cystic structures mainly originate from either the gastrointestinal tract or the genitourinary tract [ 29 ]. The location, morphology, tension of the cyst, the wall thickness, motility, and dynamic changes are the main identification points for fetal abdominal cysts ( Table 4 ).…”

Background. The purpose of this study is to evaluate the accuracy of prenatal MRI in diagnosing choledochal cysts (CDC), evaluate the sensitivity and specificity of MRI signs in the diagnosis of fetal CDC, and first compare the trend of size of CC between prenatal and postpartum. Methods. A total of 18 fetal who were diagnosed with CDCs through prenatal MRI were enrolled in the study. We summarized and analyzed the prenatal clinical data and prognosis information of prenatal and postpartum surgery, then compared the sensitivity, specificity, and diagnostic accuracy of various signs of MRI and postpartum MRCP diagnosis of CC. Finally, we tried to compare the earliest prenatal detection of common bile duct cysts with the size of surgery, and calculated the growth rate of common bile duct cysts for the first time. Results. All 18 patients were delivered in our institution. Among these patients, 14 were confirmed with CDCs after postpartum surgery, two patients had CDCs that disappeared, and two patients were confirmed with cystic biliary atresia (CBA) through the Kasai operation. Furthermore, 13 patients with CDCs and two patients with CBA underwent MRCP before the operation, and one patient with CDCs ruptured at birth and underwent ultrasound diagnosis. The sensitivity and diagnostic compliance of prenatal MRI signs for the location were higher when compared to postnatal MRCP (100% vs. 76.9% and 83.3% vs. 66.7%): the cyst was located at the porta hepatis, which was higher than the lowest edge of the liver, and parallel to the hepatoduodenal ligament. Conclusion. Prenatal MRI is higher than that of US for diagnosing CDCs, specifically in identifying the location of the cyst and confirming the origin of the cyst. The length, width, and size of the CDC become slightly bigger in our study.

“…El quiste de colédoco presentado constituye el primero informado en nuestra institución. En Occidente, tiene una tasa de frecuencia de aproximadamente 1 cada 2 millones de recién nacidos vivos (7) , y predomina en el sexo femenino (4:1 o más), como ocurrió con el recién naci- • Tipo I, el más común (70 a 80%), consiste en la dilatación quística del colédoco con la vía biliar intrahepática normal; la dilatación puede ser esférica (Ia), segmentaria (Ib) o fusiforme (Ic); es prácticamente el único que puede ser diagnosticado prenatalmente por ultrasonido.…”
