We describe the clinical, radiographic, histopathologic, and ultrastructural features of a distinct neonatal lethal chondrodysplasia inherited as an autosomal recessive trait. The characteristic radiographic findings consist of flattened, hypoplastic vertebral bodies; short ribs; hypoplastic iliac bones with "a snail-like" configuration; short, broad(More)
The dyssegmental dysplasias are lethal forms of neonatal short-limbed dwarfism in which vertebral segmentation defects and short, thick, bowed long bones are the prominent radiographic features. Clinically, unusual facies, short neck, narrow thorax, cleft palate, and reduced joint mobility are commonly seen. To date, 18 cases of dyssegmental dysplasia have(More)
Chondroosseous tissue from six infants with infantile hypophosphatasia and six control infants were studied by light, transmission, and scanning electron microscopy. Alkaline phosphatase histochemical reaction of the growth plate was studied in two infants and was greatly reduced when compared to two control infants. Hypertrophic chondrocytes were increased(More)
We have studied the light microscopic, transmission, and scanning electron microscopic (SEM) findings in 13 cases of thanathophoric dysplasia (TD) and 4 control infants. In the TD growth plate, areas with less abnormal cartilage and bone alternated with areas of severely abnormal cartilage and bone. These latter abnormal areas were always found around(More)
Achondrogenesis has traditionally been divided into type I (Parenti-Fraccaro) and type II (Langer-Saldino). We studied the clinical, radiologic, and morphologic features of 17 cases previously diagnosed as achondrogenesis type I to define whether there is even further heterogeneity. On radiographic analysis, two distinct groups of patients were defined(More)
Fibrochondrogenesis is a distinct, neonatally lethal, short-limb skeletal dysplasia which was first described in a single patient in 1978. We report the radiographic and morphologic studies of 2 additional unrelated stillborn infants with fibrochondrogenesis. This syndrome has distinct radiographic and chondro-osseous morphologic defects different from(More)
Ultrasonographic and radiographic evaluation of a fetus at risk for osteogenesis imperfecta (O.I) type III was performed. Real-time ultrasound measurements at 15 weeks gestation were interpreted as normal, but at 20 and 22 weeks of gestation revealed marked shortening of the long bones and deformity of the femurs. The findings were confirmed by fetal(More)
