Prenatal Diagnosis of Hypochondroplasia: Three-Dimensional Multislice Computed Tomography Findings and Molecular Analysis

Prenatal Diagnosis of Hypochondroplasia: Three-Dimensional Multislice Computed Tomography... We report the first case of sporadic hypochondroplasia diagnosed in utero by computed tomography (CT) three-dimensional (3D) imaging and molecular analysis at 38 weeks’ gestation. Prenatal sonographic examinations performed at 32 and 35 weeks’ gestation revealed a rhizomelic shortness of the long bones (femur and humerus) with macrocephaly. Based on these findings, a nonlethal form of skeletal dysplasia was suspected and a multislice CT imaging with 3D reconstruction was performed depicting skeletal abnormalities which suggested hypochondroplasia. The prenatal diagnosis was confirmed by DNA mutation analysis of the fibroblast growth receptor 3 gene. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fetal Diagnosis and Therapy Karger

Abstract

We report the first case of sporadic hypochondroplasia diagnosed in utero by computed tomography (CT) three-dimensional (3D) imaging and molecular analysis at 38 weeks’ gestation. Prenatal sonographic examinations performed at 32 and 35 weeks’ gestation revealed a rhizomelic shortness of the long bones (femur and humerus) with macrocephaly. Based on these findings, a nonlethal form of skeletal dysplasia was suspected and a multislice CT imaging with 3D reconstruction was performed depicting skeletal abnormalities which suggested hypochondroplasia. The prenatal diagnosis was confirmed by DNA mutation analysis of the fibroblast growth receptor 3 gene.
