Abstract

A pregnant woman with no previous routine pregnancy follow-up referred to our obstetrics clinic. Ultrasonography revealed the presence of a fetal heartbeat 26 weeks and 4 days old. Polyhydramnios, omphalocele, a diaphragmatic hernia, left ventricular hypoplasia, an occipital bone defect, a fetal head in severe retroflexion, and exaggerated cervicothoracic lordosis were detected in the fetus. After obtaining parental consent, the board decided to terminate the pregnancy. An examination performed after the termination revealed that the fetus was female and weighed 780 g. The first phalanx of the left thumb was hypoplastic. An X-ray examination showed coat hanger–shaped costal fusions and cranial structures consistent with iniencephaly. Fetus karyotyping revealed a normal 46, XX female karyotype. We speculate that this case represents a variant of Gershoni-Baruch syndrome.

 Introduction



Although omphalocele and diaphragmatic hernias can be isolated disorders, in approximately 50% of cases, they co-occur with other anomalies.[1],[2] Radius and finger anomalies can also be added to multiple malformation syndromes, such as Fanconi aplastic anemia and Balci-Gershoni-Baruch syndrome (GBS). A combination of these anomalies, along with a neural tube defect, can be defined as a schisis association. The most common accompanying neural tube defects are anencephaly and encephalocele.[3] Here, we report a combination of omphalocele, diaphragmatic hernia, cardiac abnormalities, finger abnormalities, and iniencephaly that has not been previously described in the literature and provide a probable diagnosis.

 Case Report



A 42-year-old gravida 8, parity 7 pregnant woman with no previous pregnancy follow-up visited our clinic for an obstetric appointment. She had no consanguinity with her spouse and no pathology in her obstetric history. Obstetric ultrasonography revealed a fetal heartbeat 26 weeks and 4 days old. A detailed examination revealed polyhydramnios, omphalocele containing a bowel segment, a diaphragmatic hernia, left ventricular hypoplasia, an occipital bone defect, a fetal head in severe retroflexion, and exaggerated cervicothoracic lordosis [Figure 1]. Consultation was provided to the family by the Department of Obstetrics and Gynaecology Committee, and a decision was made to terminate the pregnancy. The termination was approved by the Obstetrics and Gynaecology Committee of the Medical Faculty of Adiyaman University. Samples were taken from the parents at the same time for chromosome analysis. A physical examination conducted after the termination showed that the fetus was a 780-g female [Figure 2]. In addition to the ultrasonography findings, hypoplasia of the left thumb's first phalanx and iniencephaly (short spine and neck, mandibular skin touching the chest, wide head structure at retroflexion, micrognathia, and low-set ears) were observed. An X-ray examination revealed coat hanger–shaped costal fusions but no anomalies in the radius-ulna or lower extremities [Figure 3]. Fetal cytogenetic analysis revealed a normal 46, XX female karyotype.{Figure 1}{Figure 2}{Figure 3}

 Discussion



GBS is a rare multiple congenital malformation complex. Patients may be misdiagnosed until the underlying etiology is known. Gershoni-Baruch described a complex disease with diaphragmatic hernia, omphalocele, radial beam defects, and cardiovascular abnormalities.[4] Omphalocele can be defined as a physiological defect in the midgut returning to the abdominal cavity in the early stage of fetal development. It is associated with other system anomalies at a rate of 27%–63%[5],[6] and is most commonly accompanied by musculoskeletal anomalies (23.5%). Omphalocele can also be accompanied by gastrointestinal system ( 10.6%), central nervous system (CNS) (15.1%), and urinary system abnormalities (17.4%) and diaphragmatic hernia (5.3%). Chromosomal anomalies are also present at a rate of 7.5%–46.9%, the most common being trisomy 18.[5],[7],[8]

Many cases presenting with omphalocele or CNS and vertebral anomalies have been reported in the literature. Cases associated with vertebral anomalies are thought to belong to the vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula and/or esophageal atresia, renal and radial anomalies, and limb defects association spectrum. However, CNS anomalies, such as iniencephaly and anencephaly, are not currently thought to be included in this association. Omphalocele can also be found in the omphalocele-exstrophy-imperforate anus-spinal defects complex, which generally includes genitourinary and skeletal anomalies in addition to gastrointestinal system anomalies, such as omphalocele.[9] CNS anomalies are rarer. Common CNS anomalies include Chiari malformation, cerebral cortical atrophy, and periventricular leukomalacia.

Radial ray defects have been reported as part of many syndromes and associations. However, combinations of omphalocele and radial ray defects have rarely been identified.[4],[10],[11],[12] The radial ray defects in these cases belong to a wide spectrum, including a simple thumb anomaly, radioulnar synostosis, and the absence of a radius. Although genetic inheritance could not be ascertained in all these cases, some cases were thought to be X-linked dominant (“spectrum of schisis defects”).[13] Autosomal recessive inheritance patterns have also been identified.[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14] Disorders that include omphalocele and radial ray defects have many variations but can collectively be named Balci–GBS, after the authors who first identified the disorder.[15] Our case findings are similar to those of other disorders in terms of differential diagnosis but differ due to the presence of iniencephaly [Table 1]. An omphalocele, thumb anomaly, diaphragmatic hernia, and cardiac anomaly (left ventricular hypoplasia) association have rarely been reported in the literature. CNS anomalies are rarely found in this disorder. Encephalocele is the most common. Our case had the classic face, neck, and cerebral form of iniencephaly. The genetic factors involved in most GBS cases are unknown. The inheritance of GBS is complex and not completely understood.{Table 1}

More case reports and genetic analyses are needed to better explain the clinical features and underlying genetic causes of GBS. To identify the genetic causes of this syndrome, it seems necessary to perform whole-exome sequencing (WES), a new-generation sequencing technology, in terminated fetuses or in newborns. According to the WES results of the fetus, it is necessary to examine the pathogenic variant in the mother and father.
