The primary objective in modern obstetrics and prenatal diagnosis is to predict risks of congenital abnormalities. The aim of the research was to assess the correlation between selected oxidative stress biomarkers with the risk of foetal chromosomal aberration evaluated at the first trimester screening. A series of studies show that balanced free radical activity and oxidative homeostasis are essential for proper bodily growth and function. Reactive oxygen species (ROS) may be one of the factors associated with disruption of cell cycle and tissue development, thus leading to developmental abnormalities...

Here we present an extremely rare case of giant infantile hemangiopericytoma (HPC) of the tongue diagnosed prenatally by fetal ultrasonography and MR imaging. Due to airway stenosis, the patient was delivered by the ex utero intrapartum treatment (EXIT) procedure at 36 weeks of pregnancy. Initial diagnosis was infantile hemangioma based on physical examination, diagnostic imaging and the high incidence of hemangioma. The tumor was resistant to conservative treatments. Due to severe tumor hemorrhage, the nutrient vessel was embolized by endovascular treatment on the 73th day after birth...

Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst...

Brain lesions and malformations have been described on ultrasonography of prenatal Zika infection; however, there are scarce reports about fetal magnetic resonance (MR) findings. We report 3 cases of fetuses with confirmed intrauterine Zika virus infection evaluated by ultrasound and fetal MR. Various morphometric measurements were assessed and brain maturation was calculated with the fetal total maturation score. Fetuses with prenatal Zika virus infection showed retardation in brain maturation indexes evaluated by fetal MR...

The Neu-Laxova syndrome is a rare autosomal recessive condition associated with neuro-ectodermal abnormalities and other patterns of severe malformations leading to prenatal or early postnatal lethality. Association with kyphosis is an extremely rare finding. A fetus born from a 25-year-old gravida at 30 weeks gestation was diagnosed with Dandy Walker syndrome with severe intrauterine growth restriction on ultrasonography. On post-mortem examination after termination of pregnancy, the fetus showed facial dysmorphology with microcephaly, smooth shiny skin and kyphosis...

We present an atypical association of SCN2A epileptic encephalopathy with severe cortical dysplasia. SCN2A mutations are associated with epileptic syndromes from benign to extremely severe in absence of such macroscopic brain findings. Prenatal MRI (Magnetic Resonance Imaging) in a 32 weeks fetus, with US (Ultrasonography) diagnosis of isolated ventriculomegaly showed CNS (Central Nervous System) dysplasia characterized by lack of differentiation between cortical and subcortical layers, pachygyria and corpus callosum dysgenesis...

Postmortem magnetic resonance imaging (MRI) is emerging as a valuable tool to accompany traditional autopsy and has potential for use in cases when traditional autopsy is not possible. This case report will review the use of postmortem MRI with limited tissue sampling to differentiate between metastatic neuroblastoma and hepatoblastoma which could not be clearly differentiated with prenatal ultrasound, prenatal MRI, or emergent postnatal ultrasound. The mother presented to our institution at 27 weeks gestation after an obstetric ultrasound at her obstetrician's office identified a large abdominal mass...

Perinatal testicular torsion, defined as torsion occurring in the prenatal period or in the first month after birth, accounts for 10% of all cases of testicular torsion in pediatric patients. Most are extravaginal, and intravaginal torsion is rare. Its management is controversial, due to the low viability of the testis and the possibility of bilateral torsion. Ultrasonography is the method of choice to study testicular torsion. Combining B-mode and power Doppler imaging facilitates a fast reliable diagnosis...
