Achondrogenesis radiograph

Infants with achondrogenesis, type 2 have short arms and legs, a small chest with short ribs, and underdeveloped lungs. Achondrogenesis, type 2 is a subtype of collagenopathy, types II and XI. This condition is also associated with a lack of bone formation (ossification) in the spine and pelvis. Typical facial features include a prominent forehead, a small chin, and, in some cases, an opening in the roof of the mouth (a cleft palate). The abdomen is enlarged, and affected infants often have a condition called hydrops fetalis in which excess fluid builds up in the body before birth. The skull bones may be soft, but they often appear normal on X-ray images. In contrast, bones in the spine (vertebrae) and pelvis do not harden.

This posteroanterior (PA) view radiograph of an infant with achondrogenesis type II shows the relatively large calvaria with normal cranial ossification, short and flared thorax, bell-shaped cage and shorter ribs without fractures, relatively well ossified iliac bone with long crescent-shaped medial and inferior margins, and short tubular bones. The sacrum, pubis, and ischium are not visible. (from fuckyeahmedicalstuff)
