Abstract:
We report an apparently previously undescribed lethal skeletal dysplasia, clinically resembling achondrogenesis, but with distinct radiologic and chondro-osseous morphologic features. These comprise bifid distal ends of the long bones of the limbs, absent vertebral body ossification, a unique "baby rattle" pelvic configuration with tall and broad ilia, absent endochondral ossification, regions of mesenchymal cells within the resting cartilage, and abnormal mesenchymal ossification.
