We present the prenatal diagnosis of a vein of Galen aneurysm in a 34-week fetus. The aneurysm was 8 x 3.5 x 3 cm in dimension, and located posterior to the third ventricle. Color flow examination revealed a turbulent flow in the lesion. There was significant cardiomegaly. Prenatal ultra-fast magnetic resonance imaging was used to view the malformation in three dimensions. Although the pregnanc...

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 cystic adenomatoid malformation (CCAM) is a rare pulmonary malformation resulting from excessive overgrowth of the terminal bronchioles. We present two CCAM case studies: type I (macrocystic) and type III (microcystic), diagnosed by antenatal ultrasonography at 31 and 21 weeks' gestation, respectively. In the former, multiple dilated cystic masses in the fetal left lung, with polyhyd...

Congenital high airway obstruction syndrome is a rare fetal anomaly with characteristic constellation of prenatal findings on ultrasound and MRI. The typical triad of imaging features are enlarged and echogenic lungs, flattening or inversion of diaphragm and fetal hydrops. Early prenatal recognition of congenital high airway obstruction syndrome by ultrasound and/or MRI is mandatory for the app...

holoprosencephaly is a rare intracranial abnormality. the incidence of holoprsencephaly is between 0.56-0.63 of 10,000 live-born infants10. it has classified into three degrees, alobar, semilobar and lobar. in this case report we are introducing a case of holoprosencephaly, in 13 weeks of pregnancy which was twin. we could identified this abnormality and the reduction was done in the appropriat...

Abstract This second part on Doppler sonography in prenatal medicine and obstetrics reviews its clinical applications. While this has not become the initially anticipated screening tool, it is used for diagnosis surveillance of a variety fetal pathologies. For example, sonography-based determination uterine artery blood flow indices an important parameter first trimester multimodal preeclampsia...

Cloacal dysgenesis sequence (CDS) is a lethal and rare congenital malformation; usually requiring termination of gestation. As prenatal ultrasonography remains a method with doubtable results, we used Fetal Magnetic Resonance Urography (FMRU) for the evaluation of a fetus at 18 weeks of gestation, suspected to cloacal anomalies. Prenatal imaging of the patient; showed smooth perineum, bilateral...
