“…There have been few reports describing a change in cyst size during fetal life. All of Weeks of Gestation them found no change in choledochal cyst size [1,[5][6][7], The communication between common bile duct and duo denum, into which the bile could be excreted, might cause no enlargement of the cyst. On the other hand, it was reported that in many cases the cyst size had increased after birth.…”

Both choledochal cyst and congenital biliary atresia (type I cyst) may share the same ultrasonographic pattern. We report 2 cases which were shown to have cystic structures on the upper abdomen by antenatal ultrasonography. The size of the choledochal cyst found at 24 weeks’ gestation increased steadily as gestational age advanced. But the size of the cyst in congenital biliary atresia found at 29 weeks’ gestation remained unchanged throughout the remaining pregnancy. Cyst enlargement, therefore, may suggest the possibility of a choledochal cyst.

“…[30][31][32][33][34] These three types of cyst, however, occur in locations that differ from that of the cyst in this case. Among the other miscellaneous causes of an intraabdominal cystic mass in the fetus is a presacral cystic teratoma.…”

A one-month-old girl was admitted to the hospital because of an intraabdominal mass.After a 42-week gestation, the infant had been delivered by cesarean section because of cephalopelvic disproportion. There were no complications during the pregnancy or delivery. A routine ultrasonographic examination ( Fig. 1), performed during the 28th week of pregnancy, showed a multiseptated cystic mass in the midabdomen. An ultrasonographic study during the 29th week of pregnancy showed the same mass slightly to the left of the midline. Another prenatal ultrasonographic examination at 30 weeks also showed the cystic abdominal mass near the midline. The infant weighed 3.76 kg at birth. She was fed a commercial formula with iron and was healthy from birth, although her parents described her as "colicky." Occasional constipation was noted; she did not vomit. Thirteen days before admission a computed tomographic (CT) scan of the abdomen (Fig. 2) revealed a cystic mass, 5 by 5 cm, that displaced the bowel to the left side and appeared to be unrelated to the genitourinary system or the liver. She was admitted to the hospital.The heart rate was 160, and the respirations were 24. The weight was 4.15 kg.On physical examination the infant appeared well. The head was normal, and the neck was supple. The lungs and heart were normal. The abdominal examination was normal; no organs or mass was felt. The external genitalia were normal, and rectal examination disclosed no pelvic or sacral mass. The neurologic examination was normal.The hematocrit was 34.9 percent, the white-cell count 13,200 per cubic millimeter, and the platelet count 505,000 per cubic millimeter. The mean corpuscular volume was 84 m m 3 .A diagnostic procedure was performed.

“…Fetal choledochal cyst usually appears as a fluid-filled, right upper quadrant, anechoic mass in the region of the porta hepatis (Lugo-Vincente, 1995;Schroeder et al, 1989;Marchildon, 1988;Wiedman et al, 1985;Howell et al, 1983;Frank et al, 1981;Dewbury et al, 1980;Filly and Carlsen, 1976). Demonstration of continuity with the gall bladder or hepatic ducts or associated dilatation of intra-and extrahepatic ducts further aids diagnosis (Elrad et al, 1985;Frank et al, 1981).…”

Early Prenatal Diagnosis of Choledochal Cyst

Unrecognized biliary tract obstruction due to choledochal cysts or biliary atresia can result in significant morbidity and mortality. Diagnosis in utero of choledochal cyst allows prompt postnatal diagnostic evaluation and appropriate surgical therapy to be instituted early in life. This may minimize the potential complications of cholangitis, cirrhosis, and liver failure in infants with choledochal cysts.
