Fetal Thigh Circumference Nomograms Across Gestational Ages: A Retrospective Study.

: Fetal thigh circumference (ThC) may be a valuable parameter for assessing fetal growth. Thus, this study aimed to establish reference ranges for ThC across gestational ages (GA). : This retrospective study included singleton pregnancies between 12 and 38 weeks of gestation.

Endometrial Osseous Metaplasia: A Retrospective Analysis and Systematic Review.

Endometrial osseous metaplasia is a rare condition defined as the presence of heterotopic bone in the endometrium. A retrospective, monocentric analysis was conducted, including patients with endometrial osseous metaplasia, and a systematic review of the literature was performed. The retrospective analysis included 10 cases.

The unpredictable clinical course of an abdominal cyst diagnosed in the prenatal period: A case report.

Enteric duplication cysts are rare congenital malformations of the gastrointestinal tract. Prenatal diagnosis can be achieved through ultrasound, which may reveal a cystic mass, though the differential diagnosis is broad. We report a case in which the prenatal ultrasound detection of an abdominal cystic mass prompted postnatal magnetic resonance imaging, leading to the diagnosis of an enteric duplication cyst.

Fetal Cerebellar Area: Ultrasound Reference Ranges at 13-39 Weeks of Gestation.

Background And Objectives: The present study aims to provide prenatal 2-dimensional ultrasonographic (2D-US) nomograms of the normal cerebellar area.

Materials And Methods: This is a prospective cross-sectional analysis of 252 normal singleton pregnancies, ranging from 13 to 39 weeks of gestation. The operator performed measurements of the fetal cerebellar area in the transverse plane using 2D-US.

Prenatal Diagnosis of an Intrathoracic Left Kidney Associated with Congenital Diaphragmatic Hernia: Case Report and Systematic Review.

Introduction: A congenital intrathoracic kidney (ITK) is a rare anomaly that is recognized to have four causes: renal ectopia with an intact diaphragm, diaphragmatic eventration, diaphragmatic hernia, and traumatic diaphragmatic rupture. We report a case of a prenatal-diagnosed ITK related to a congenital diaphragmatic hernia (CDH) and conducted a systematic review of all cases of the prenatal diagnosis of this association.

Case Presentation: A fetal ultrasound scan at 22 gestational weeks showed left CDH and ITK, hyperechoic left lung parenchyma, and mediastinal shift.

Omphalocele Secondary to Spontaneous Rupture of Allantoic Cyst in the Third Trimester of Pregnancy.

Objective: We report the first case in which the onset of omphalocele was after the spontaneous rupture of an allantoic cyst. We hypothesize a causal link between the spontaneous rupture of the cyst and the herniation of the viscera. .

Prenatal diagnosis of a novel pathogenic variation in the ACAN gene presenting with isolated shortening of fetal long bones in the second trimester of gestation: a case report.

Background: Heterozygous mutations of the ACAN gene are a major cause of different evolutive growth defects in the pediatric population, but were never described as a cause of fetal skeletal dysplasia.

Case Presentation: A G1 at 21w + 3d came to our institution for the second-trimester ultrasound and a skeletal dysplasia with prevalent involvement of limb's rhizomelic tracts was suspected. Amniocentesis followed by CGH-array was performed, with normal results.

Prenatal ultrasound diagnosis of duplication gallbladder: a multicenter study.

Background: Gallbladder duplication is a rare anatomic anomaly characterized by the presence of an accessory gallbladder.

Objective: To appraise the prevalence and significance of prenatal diagnosis of duplication of gallbladder in a multicenter study.

Methods: This was a multicenter case series with literature review.

Intrahepatic persistent fetal right umbilical vein: a retrospective study.

Introduction: To appraise the incidence and value of intrahepatic persistent right umbilical vein (PRUV).

Methods: This was a single-center study. Records of all women with a prenatal diagnosis of intrahepatic PRUV were reviewed.

Prenatal ultrasound diagnosis of fetal chest wall cystic lymphangioma: An Italian case series.

Fetal lymphangioma is a rare congenital malformation of lymphatic system that involve the skin and the subcutaneous tissue. The vast majority of the lymphangioma occurs in the neck. More rarely lymphangiomas may occur in the axillary region, including chest wall.

Proliferative vasculopathy and hydranencephaly-hydrocephaly syndrome or Fowler syndrome: Report of a family and insight into the disease's mechanism.

Background: Fowler syndrome is a rare autosomal recessive disorder characterized by hydranencephaly-hydrocephaly and multiple pterygium due to fetal akinesia. To date, around 45 cases from 27 families have been reported, and the pathogenic bi-allelic mutations in FLVCR2 gene described in 15 families. The pathogenesis of this condition has not been fully elucidated so far.

Satisfactory rate of post-processing visualization of fetal cerebral axial, sagittal, and coronal planes from three-dimensional volumes acquired in routine second trimester ultrasound practice by sonographers of peripheral centers.

Objective: The aim of this study was to evaluate the feasibility to visualize central nervous system (CNS) diagnostic planes from three-dimensional (3D) brain volumes obtained in ultrasound facilities with no specific experience in fetal neurosonography.

Methods: Five sonographers prospectively recorded transabdominal 3D CNS volumes starting from an axial approach on 500 consecutive pregnancies at 19-24 weeks of gestation undergoing routine ultrasound examination. Volumes were sent to the referral center (Department of Obstetrics and Gynecology, Università Roma Tor Vergata, Italy) and two independent reviewers with experience in 3D ultrasound assessed their quality in the display of axial, coronal, and sagittal planes.

Satisfactory rate of postprocessing visualization of standard fetal cardiac views from 4-dimensional cardiac volumes acquired during routine ultrasound practice by experienced sonographers in peripheral centers.

The aim of this study was to evaluate the feasibility of visualizing standard cardiac views from 4-dimensional (4D) cardiac volumes obtained at ultrasound facilities with no specific experience in fetal echocardiography. Five sonographers prospectively recorded 4D cardiac volumes starting from the 4-chamber view on 500 consecutive pregnancies at 19 to 24 weeks' gestation undergoing routine ultrasound examinations (100 pregnancies for each sonographer). Volumes were sent to the referral center, and 2 independent reviewers with experience in 4D fetal echocardiography assessed their quality in the display of the abdominal view, 4-chamber view, left and right ventricular outflow tracts, and 3-vessel and trachea view.
