“…Matsubara et al reported that enlargement of the cyst suggests the possibility of CC [7]. On the other hand, Casaccia et al reported that a small anechoic cyst in the hepatic hilum is suspicious of BA [2]. In our case, the cyst did not enlarge, was anechoic, and was relatively small, which are prenatal characteristics indicative of BA.…”

Disappearing cyst of the hepatic hilum in uncorrectable biliary atresia

et al. 2005

A 2-month-old boy with biliary atresia (BA) with an extremely rare prenatal history is reported. A cystic lesion in the hepatic hilum was diagnosed during prenatal ultrasonography at 20 weeks' gestation. However, it disappeared during later prenatal observation. He was diagnosed with an uncorrectable type of BA after a massive subdural hemorrhage at the age of 66 days. A fetus suspected of having a cyst of the biliary tree should be followed even after the cyst has disappeared spontaneously.

“…The antenatal diagnoses of these cases were duodenal atresia in 1, mesenteric cyst in 1, ovarian cyst in 4, megacystis in 2, renal cyst in 1, hepatic cyst in 2, and choledochal cyst in 1. Mesenteric, ovarian and renal cysts may resolve during intrauterine life, and a normal gallbladder is occasionally mistaken for a pathological intra-abdominal cyst [1,15] . Other than these misdiagnoses, which did not warrant any change in the management of the pregnancy, even conditions such as duodenal atresia or megacystis may be diagnosed falsely.…”

Introduction: The differential diagnosis of an abdominal cyst can be challenging, and an accurate diagnosis is crucial for optimal antenatal management. The aim of this study was to compare the ante- and postnatal diagnoses of cases with abdominal cyst and to determine the diagnostic accuracy of ultrasonography. Material and Methods: A database review was performed regarding the diagnosis of fetal abdominal cyst covering the period 2002–2009. Structural characteristics and localizations of the cysts in the abdomen were recorded. Ante- and postnatal diagnoses were classified into systems according to the origin of the cyst and were compared. Perinatal outcomes were obtained for all cases. Results: 71 cases with an abdominal cyst were identified. The mean gestational age at the time of diagnosis was 25 ± 5.1 weeks. In 9 cases, there were extra-fetal structural abnormalities, and in 5 cases a chromosomal abnormality was determined. Seven pregnancies were terminated. Overall spontaneous mortality was 11/64 (17%). In 12/64 cases (18%), the cyst resolved at birth. After birth, nearly half of the cases required surgical correction and of these, 20% died. Sensitivity, specificity and positive predictive value of ultrasonography in identifying the system of origin were 88.1, 95.7 and 92.0%, respectively, with a 4.1% false-positive rate. Conclusion: Incorporation of different disciplines in the counseling, management and postpartum follow-up is crucial. Postnatal physical examination of fetuses with an abdominal cyst will help to prevent unnecessary surgery.

“…The literature about prenatal diagnosis of fetal hepatic cyst is limited. [1][2][3][4] Moreover, there are only a few reports of early second-trimester sonographic diagnosis of fetal liver cysts. [5][6][7] We therefore summarized our experience of diagnosing and following fetal hepatic cysts.…”
