Object The use of fetal MR imaging for the in utero evaluation of pathological conditions of the CNS is widely accepted as an adjunct to fetal ultrasonography studies. Magnetic resonance imaging is thought to characterize CNS anomalies better, and to provide a more exact diagnosis and accurate prognosis. The purpose of this study was to determine the role of and indications for fetal MR imaging in evaluating fetuses with different CNS abnormalities that were seen initially on prenatal sonograms. Methods Over a 3-year period, fetuses with prior sonographic evidence of CNS abnormalities who consequently received prenatal MR imaging at Columbus Nationwide Children's Hospital within 2 weeks of the fetal ultrasonography study were included in this study. For each patient, radiological reports from both studies were reviewed, analyzed, and compared with the findings at postnatal imaging or physical examination. Results of the 2 modalities were then compared in terms of diagnostic accuracy. Results Twenty-six fetuses were included in this study on the basis of an in utero sonogram showing a CNS anomaly. Their gestational age ranged from 17 to 35 weeks, with a mean of 25 weeks at the time of fetal ultrasonography. Hydrocephalus was identified in 16 fetuses, 6 had evidence of a spinal dysraphic defect, 2 had holoprosencephaly, 1 had an encephalocele, and 1 had multiple body abnormalities requiring detailed CNS evaluation. Twenty-five of the fetuses were correctly evaluated as having abnormal CNS findings on both fetal ultrasonography and fetal MR imaging. Fetal ultrasonography provided a correct prenatal diagnosis in 20 cases, whereas fetal MR imaging was correct in 22 cases. There were 9 cumulative false-positive results for fetal ultrasonography and 7 for fetal MR imaging, whereas for false-negative results there were a total of 34 and 19, respectively. Conclusions Fetal MR imaging is more sensitive in detecting fetal CNS abnormalities, but its ability to provide a correct prenatal diagnosis is only marginally superior to fetal ultrasonography. Moreover, fetal MR imaging is not exempt from misdiagnosis, and still shows a significantly high rate of false-negative results. Particularly for spinal dysraphic defects, fetal MR imaging does not seem to add important diagnostic or prognostic details when compared with fetal ultrasonography.

Abstract Purpose To explore the diagnostic value of systematic fetal ultrasonography for trisomy 18 (T18) syndrome before 16 weeks gestation. Methods A total of 12 fetuses with T18 were selected as research subjects and their nuchal translucency (NT) screening and fetal systematic ultrasonographic images acquired at 11–15 weeks were retrospectively analyzed. Results In the 12 fetuses’ NT screening, ten fetuses showed NT thickening, one showed nuchal cystic hygroma, four showed reversed a-wave ductus venosus flow, and three showed omphalocele. The most common anomalies on the systematic ultrasonography before 16 weeks gestation were cardiac defects (12/12, 100%), omphalocele (4/12, 33.3%), limb anomalies (5/12, 41.7%), and facial anomalies (3/12, 25.0%). Seven of the 12 fetuses had multiple structural malformations: three had two structural malformations (25.0%), three had three structural malformations (25.0%), and one had four structural malformations (8.3%). Conclusion Systematic fetal ultrasonography before 16 weeks gestation can detect most of the structural malformations of T18, effectively shortening the prenatal diagnosis time. It is therefore of great importance for reducing the birth rate of children with T18 and minimizing the physical and mental damage to mothers and their families.

Meconium periorchitis is a rare disorder caused by fetal meconium peritonitis, with subsequent passage of meconium into the scrotum via a patent processus vaginalis. To date, clinical significance of meconium periorchitis for the prenatal diagnosis of meconium peritonitis and prediction for postnatal surgery remains to be determined. We present a clinical course of a fetus presenting with meconium periorchitis induced by meconium peritonitis. At 28 weeks’ gestation, fetal ultrasonography indicated fetal ascites associated with bilateral hydrocele and peritesticular calcification without other signs of meconium peritonitis. The pregnancy was uneventful until delivery and the infant was delivered at 37 weeks’ gestation. No abdominal distension was observed at birth, and radiography did not reveal any abdominal calcification except for scrotal calcification. Abdominal distension was observed 3 days after birth and laparotomy was performed. The diagnosis of meconium peritonitis was confirmed at surgery. Our case illustrated that careful examination of the scrotum during fetal life was helpful for prenatal diagnosis of meconium peritonitis as well as postnatal management.

Klippel-Trenaunay-Weber syndrome is a rare cutaneous vascular disorder characterized by the presence of multiple hemangiomata, arteriovenous fistulas, and limb hypertrophy. We report the prenatal sonographic findings in a case of Klippel-Trenaunay-Weber (KTW) syndrome including fetal limb hypertrophy and large subcutaneous cystic lesions. Prenatal diagnosis is possible by ultrasound examination and recognition important for prevention of complications and future management.

High Index Of Suspicion

We describe a postnatally diagnosed case of Walker-Warburg syndrome – a form of congenital muscular dystrophy with lissencephaly and eye abnormalities. We reviewed the literature to highlight its clinico-radiological diagnostic features and discuss the difficulties encountered with prenatal diagnosis, especially in cases with no positive family history. An increased awareness of this rare but lethal condition, and a high index of suspicion during routine antenatal ultrasound, could prompt further advanced fetal ultrasonography and magnetic resonance imaging, and aid in timely prenatal diagnosis, management, and counseling.
