Prenatal Ultrasound and MRI Diagnosis of Jeune Syndrome Type I (Asphyxiating Thoracic Dystrophy) with Histology and Post-Mortem Three-Dimensional CT Confirmation

Abstract

Asphyxiating thoracic dystrophy (ATD) also known as Jeune syndrome is a rare autosomal recessive multisystem disorder with an incidence estimated in 1:100.000–130.000 live births. Associated findings may include hepatic fibrosis and renal cysts. A prenatal ultrasound and MRI diagnosis performed in the early second-trimester of pregnancy is reported together with DNA analysis. Post-mortem diagnostic investigations such as radiograph and three-dimensional CT scan and histology have been useful in the final diagnosis of this rare skeletal dysplasia.
