Project description:Fetal intestinal volvulus is a rare condition that can lead to hemorrhage, bowel necrosis, and urgent surgical treatment after birth. Thus, prompt diagnosis and treatment are essential to avoiding fetal or neonatal demise. Prenatal ultrasound is a keystone tool in the diagnostic course. However, sonographic findings tend to be non-specific, with limited understanding of the pathophysiology behind their atypical presentation. With a literature review and a case series, we aim to optimize the antenatal diagnosis and management of this rare but life-threatening condition. Six cases from our institution were retrospectively analyzed over 12 years. A literature review was conducted until December 2022. A total of 300 articles matched the keyword "Fetal volvulus", and 52 studies were eligible for the review. Our 6 cases are added to the 107 cases reported in the literature of fetal intestinal volvulus with antenatal ultrasound assessment and without associated gastroschisis or omphalocele. Several prenatal symptoms and ultrasound markers, even if not specific, were more frequently reported. Different experiences of management were described regarding follow-up, the timing of delivery, the mode of delivery, and surgery outcomes. This paper highlights the importance of suspecting and assessing fetal volvulus at routine ultrasound scans, describing the most frequent antenatal presentations and management in order to improve fetal and neonatal outcomes.

Prenatal diagnosis of fetal peters' plus syndrome: a case report.

Project description:Peters' plus syndrome is a rare but clinically recognizable autosomal recessive ocular genetic syndrome. Diagnosis during the fetal life is challenging due to the presence of nonspecific findings such as ventriculomegaly in the growth-retarded fetuses. We report the first case of fetal Peters' plus syndrome from India, where fetal ultrasound and the family history were helpful in providing a clue to the diagnosis that was confirmed later on by the DNA analysis.

Fetal-MRI prenatal diagnosis of severe bilateral lung hypoplasia: alveolar capillary dysplasia case report.

Project description:Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare and lethal developmental disorder of the lung that affect both acinar structure and the intrinsic pulmonary vasculature. We report prenatal and postnatal imaging with histopathological findings of this rare condition. We, first, describe MR imaging features and discuss its role in prenatal imaging.

Prenatal diagnosis of fetal encephalomalacia after maternal diabetic ketoacidosis.

Project description:Introduction Encephalomalacia in a developing fetus is a rare and devastating neurological finding on radiologic imaging. Maternal diabetic ketoacidosis (DKA) can lead to metabolic and vascular derangements which can cause fetal encephalomalacia. Case We report the case of a 27-year-old pregnant woman with White's Class C diabetes mellitus who presented in the 25th week of gestation with DKA. Four weeks after her discharge, marked fetal cerebral ventriculomegaly was noted on ultrasound. A subsequent fetal magnetic resonance imaging (MRI) demonstrated extensive, symmetric cystic encephalomalacia, primarily involving both cerebral hemispheres. The pregnancy was continued with close fetal and maternal surveillance. The patient underwent a repeat cesarean delivery in her 37th week. The infant had a 1 month neonatal intensive care unit stay with care rendered by a multiple disciplinary team of pediatric subspecialists. The postnatal course was complicated by global hypotonia, poor feeding, delayed development and ultimately required anticonvulsants for recurrent seizures. He died at the age of 9 months from aspiration during a seizure. Discussion Although the maternal mortality from DKA has declined, DKA still confers significant neurological fetal morbidity to its survivors.

Guidelines for the prenatal diagnosis of fetal skeletal dysplasias.

Project description:The osteochondrodysplasias, or skeletal dysplasias are a genetically heterogeneous group of over 350 distinct disorders, and many of them can present in the prenatal period as demonstrated by ultrasound. Differentiating these disorders in the prenatal period can be challenging because they are rare and many of the ultrasound findings are not necessarily pathognomic for a specific disorder. However, differentiating known lethal disorders from nonlethal disorders, providing differential diagnoses before delivery, determining postdelivery management plans and ultimately determining accurate recurrences risks to the at-risk couples improves patient care. These guidelines provide an approach to a fetus suspected of manifesting a skeletal dysplasia.

Prenatal diagnosis of congenital harlequin ichthyosis with fetal MRI.

Project description:Most of the fetal deformities are caused due to genetic abnormalities. Although magnetic resonance imaging (MRI) may be used to accurately diagnose these deformities, it has been reported that gene analysis is a more accurate diagnostic method. Harlequin ichthyosis (HI) or Ichthyosis fetalis (IF) is a rare and extremely severe hereditary skin disorder with autosomal recessive inheritance. The ultrasound features have been described well and the diagnosis can be made with a fair degree of confidence. However, the final diagnosis needs to be established by prenatal invasive tests. In the present study, we describe the diagnosis of HI in the third trimester on fetal MRI referred to our department with suspicion of anterior encephalocele which was later confirmed through postnatal genetic evaluation.

Can prenatal diagnosis of parachute mitral valve be achieved? A case report of fetal parachute mitral valve.

Project description:Parachute mitral valve (PMV) is a common form of congenital mitral stenosis and is difficult to diagnose prenatally. This report describes a fetal case of PMV with coarctation of the aorta that was diagnosed at 25 weeks' gestation by echocardiography and confirmed at autopsy. We describe the ultrasonographic features in this case and present a useful sign for making a prenatal diagnosis of PMV.
