Hemifacial microsomia with spinal and rib anomalies: prenatal diagnosis and postmortem confirmation using 3-D computed tomography reconstruction

Prenatal and Neonatal Ultrasound and Magnetic Resonance Imaging Diagnosis of Sprengel's Deformity with Unusual Associations

INTRODUCTION

Sprengel's deformity is a rare congenital anomaly of the shoulder rim. It is the most common congenital anomaly of the shoulder, associated with cosmetic deformity and abnormal shoulder function. Nonsurgical management can be considered for mild cases. Surgical intervention is indicated in moderate to severe cases with the goal of improving cosmetic appearance and function. The best surgical results are obtained in children aged 3-8 years. Correct diagnosis is very important because Sprengel's deformity can be accompanied by additional abnormalities, even in mild cases, and lack of a diagnosis delays proper treatment of the child. The severity of the defect may progress, so it is important to correctly identify children with Sprengel's deformity, even those with a mild form of the defect.

CASE PRESENTATION

We report a case of prenatal sonographic diagnosis of Sprengel's deformity with additional features, as yet undescribed and missed - although visible - on prenatal magnetic resonance imaging (MRI). Cesarean delivery was performed due to preterm rupture of membranes, and a postnatal MRI confirmed the unusual constellation of Sprengel's anomaly with lateral meningocele, vestigial posterior meningocele, and lipoma tethering of the cord to the dural sac at the cervical-thoracic junction.

CONCLUSION

Diagnosis of Sprengel's deformity is possible with prenatal ultrasound. Asymmetry of the cervical spine, discontinuity of the vertebral arch and abnormal vertebral bodies, as well as the asymmetric position of the shoulder blades with the presence of an omovertebral bone are signs that can help diagnose the defect.

Genetics of non-isolated hemivertebra: A systematic review of fetal, neonatal, and infant cases

Hemivertebra is a congenital vertebral malformation caused by unilateral failure of formation during embryogenesis that may be associated with additional abnormalities. A systematic review was conducted to investigate genetic etiologies of non-isolated hemivertebra identified in the fetal, neonatal, and infant periods using PubMed, Cochrane database, Ovid Medline, and ClinicalTrials.gov from inception through May 2022 (PROSPERO ID CRD42021229576). The Human Phenotype Ontology database was accessed May 2022. Studies were deemed eligible for inclusion if they addressed non-isolated hemivertebra or genetic causes of non-isolated hemivertebra identified in the fetal, neonatal, or infant periods. Cases diagnosed clinically without molecular confirmation were included. Systematic review identified 23 cases of non-isolated hemivertebra with karyotypic abnormalities, 2 cases due to microdeletions, 59 cases attributed to single gene disorders, 18 syndromic cases without known genetic etiology, and 14 cases without a known syndromic association. The Human Phenotype Ontology search identified 49 genes associated with hemivertebra. Non-isolated hemivertebra is associated with a diverse spectrum of cytogenetic abnormalities and single gene disorders. Genetic syndromes were notably common. Frequently affected organ systems include musculoskeletal, cardiovascular, central nervous system, genitourinary, gastrointestinal, and facial dysmorphisms. When non-isolated hemivertebra is identified on prenatal ultrasound, the fetus must be assessed for associated anomalies and genetic counseling is recommended.

A Possible case of Facio-Auriculo-Vertebral sequence (FAVs) in an adult female from medieval Iceland (13th-16th Century)

OBJECTIVE

This paper presents a possible case of Facio-Auriculo-Vertebral sequence (FAVs) in an adult female from Haffjarðarey, Western Iceland (1200-1563 CE) and a brief review of associated terminology.

MATERIALS

The skeletal remains of a single adult female (HFE-A-34, 18-24 years old), excavated in 1945 by the National Museum of Iceland.

METHODS

We carried out macroscopic examination of the cranium and mandible in 2017.

RESULTS

Right side unilateral asymmetric craniofacial dysplasia was identified on the cranium and mandible of HFE-A-34.

CONCLUSIONS

This individual presents with anomalous craniofacial asymmetry consistent with a clinical diagnosis of FAVs.

SIGNIFICANCE

This paper offers a visually distinct case of an under-represented and under-documented congenital condition for future identification within paleopathology.

LIMITATIONS

Infra-cranial skeletal manifestations of FAVs would strengthen this possible diagnosis, but at this time it is not possible to definitively link the cranium and mandible of HFE-A-34 to any of the infra-cranial remains excavated from Haffjarðarey.

SUGGESTIONS FOR FURTHER RESEARCH

In addition to further clarifying the variable nature of FAVs in archaeological remains, a detailed discussion of disability and the perception of disabled individuals within the medieval North Atlantic is necessary in order to understand the lived experiences of affected individuals.
