Congenital cervical teratoma,associated with agenesis of corpus callosum and a subarachnoid cyst

Cervical teratoma is a neoplasm composed of embryonic tissues with representation of all three germ layers. We report an extremely rare case of fetal cervical teratoma presenting at 24 weeks of gestation. A submaxillary mass and agenesis of corpus callosum were identified on ultrasonography, associated with agenesis of corpus callosum and a subarachnoid cyst.

Isolated right diaphragmatic eventration mimicking congenital heart disease in utero

Diaphragmatic eventration is the upward displacement of the abdominal viscera secondary to a thin or paralytic diaphragm. Its clinical presentations and radiographic pictures are similar to those of diaphragmatic hernia. Prenatal diagnosis of diaphragmatic eventration is extremely rare. A pregnant woman was referred to us because of abnormal cardiac findings noted at 20 weeks of gestation. A diagnosis of partial anomalous pulmonary venous connection was made on the basis of our findings of right atrial enlargement with an abnormal vascular channel drainage to it. The infant was born via cesarean section at 40 weeks and developed complications of cyanosis immediately after birth. Postnatal imaging studies and surgical findings disclosed right side diaphragmatic eventration with liver and associated vasculature upward displacement into the right pleural cavity. The cardiac structure was otherwise normal. We conclude that when an abnormal vessel tracing and unexplainable cardiac chamber asymmetry is encountered, diaphragmatic eventration should be considered as one of the differential diagnoses. Correct recognition and transferral to the hospital for neonatal assistance may lead to timely and appropriate management of these fetuses. Copyright © 2005 John Wiley & Sons, Ltd.     

Prenatal diagnosis of congenital epulis by three-dimensional ultrasound and magnetic resonance imaging

Congenital epulis is a benign intraoral tumor that has rarely been diagnosed prenatally. We report a fetus with congenital epulis diagnosed by three-dimensional (3-D) ultrasound and fetal magnetic resonance imaging (MRI) at 35 weeks' gestation. We show an image of congenital epulis using a new ultrasound technique, the 3-D multislice view, which shows images similar to CT or MRI. This is a short case report of congenital epulis diagnosed prenatally by 3-D ultrasound using multislice view and MRI. Copyright © 2006 John Wiley & Sons, Ltd.     

Prenatal diagnosis of apparently isolated unilateral multicystic kidney: implications for counselling and management

Cases where initial prenatal diagnosis was made of isolated unilateral multicystic kidney (UMCK) were reviewed to determine appropriate counselling and management strategies. For the 73 cases, chromosome abnormalities, pregnancy complications and family histories were reviewed. In addition, subsequently diagnosed birth defects, and pediatric medical and surgical outcomes were available for 54 cases. Of those with outcome information available renal/genital–urinary tract abnormalities were diagnosed subsequently in 33% and non-renal abnormalities in 16% of cases. Of the non-renal abnormalities, congenital heart defects were most frequent (7%). One chromosome abnormality, a trisomy 21, was present among 32 cases where karyotypes were known (3%). Amniotic fluid volume abnormalities were present in 11 cases but not predictive of associated anomalies, with the exception of one case where polyhydramnios accompanied multiple malformations consistent with VATER association. A family history of structural renal anomalies was reported in 11 cases (20%). There were 14 cases of partial or complete involution (25%), including two cases of complete prenatal involution of the cystic kidneys. No long-term associated morbidity such as hypertension or malignancy was present in our cohort. Based on our study and corroborating literature, amniocentesis should be offered to women when a seemingly isolated UMCK is detected on routine prenatal ultrasound. Furthermore, a detailed ultrasound with careful assessment of the fetal heart and contralateral kidney is indicated at diagnosis and during the third trimester to assess for further evidence of structural abnormalities, as well as amniotic fluid volume abnormalities. Careful assessment of the newborn is indicated with appropriate speciality referral as required. Copyright © 2002 John Wiley & Sons, Ltd.
