INTRODUCTION Fetal tumors are relatively rare and the early prenatal diagnosis enables the prediction of possible complications and decision for appropriate treatment. This paper deals with the role of ultrasonography and magnetic resonance imaging in the early prenatal diagnosis of sacrococcygeal teratoma. CASE REPORT A 21-year-old primigravida was found to have a large sacrococcygeal tumor ...
Prenatal Diagnosis and Pathology of Laryngeal Atresia in Congenital High Airway Obstruction Syndrome
Congenital high airway obstruction syndrome is a rare but life-threatening condition. Therefore, prenatal diagnosis is important. The obstruction can be due to laryngeal/tracheal atresia or external compression. While a differential diagnosis with congenital cystic adenomatoid malformation (CCAM) type III may be difficult, it is still possible with ultrasonography. In this study, we report a ca...
1. Describe the purpose of the prenatal visit. 2. Recognize the significance of common abnormalities found on prenatal ultrasonography. 3. Discuss the importance of growth and maturity assessment as well as the careful examination of the newborn. 4. Delineate prevention strategies for hepatitis B, syphilis, and group B streptococcal infections. 5. Explain the basics of car seat safety and sudde...
Thanatophoric dysplasia (TD) is caused by mutation of the gene that encodes fibroblast growth factor 3 (FGFR3). Owing to the poor prognosis for TD, prenatal diagnosis is critical to optimal perinatal management. We report here a case of TD in twin pregnancy, which was prenatally diagnosed by DNA analysis following amniocentesis at 15 weeks, and was managed by selective fetal termination. Prenat...
We report the imaging findings in a case of fetal lymphangioma involving the retroperitoneum and right lower extremity, and diagnosed by ultrasonography and magnetic resonance (MR) imaging at 26 weeks of gestation. Prenatal ultrasonograms and T2-weighted single-shot fast spin-echo MR images clearly revealed an extensive, multilocular cystic mass with internal hemorrhage in the retroperitoneum e...
We report a case of fetal pericallosal lipoma occurring at the anterior interhemispheric fissure and associated with agenesis of the corpus callosum. During targeted prenatal ultrasonography at 26 weeks' gestation, the lesion was seen as a highly echogenic mass. MR imaging performed at 35 weeks' gestation and during the postnatal period revealed a pericallosal fatty mass and agenesis of the cor...
Introduction: Lymphangiomas are very rare benign tumors of the lymphatic system, appearing as uniseptate or multiseptate cystic masses, which are usually located in the cervical or axillary area. Postnatal outcome depends on the size and location of the lesion. An increasing number of such congenital abnormalities are detected on routine conventional prenatal ultrasonography. Although prenatal ...
UNLABELLED Prenatal ultrasonography has revolutionized the detection and management of many urological abnormalities. Vesicoureteric reflux (VUR) which develops in 10% to 15% of cases of prenatal hydronephrosis, is difficult to predict prenatally. While all children with prenatal hydronephrosis should undergo ultrasonography within the first few weeks of life, there seems to be controversy rega...
Congenital diaphragmatic hernia (CDH) has an incidence of approximately 1:4000 live births. Most frequently the diaphragmatic defect is a left and posterolateral (Bochdalek) one. Prenatal diagnosis is made at ultrasonography; the relevant sonographic features will be described in the paper. Cystic adenomatoid malformation of the lung (CAML), pulmonary sequestration, bronchogenic cysts, pulmonar...
Background and Aims: Fetal echocardiography is helpful in early detection of Congenital Heart Disease.Our study was conducted to evaluate the most common indications of referral and outcome in a tertiary-care fetal echocardiography practice. Methods: A Cross-sectional analysis of all pregnant women referred by obstetricians to cardiology unit for fetal echocardiography over a 1-year period (Jul...
