The radiographic differential diagnosis of juvenile chronic arthritis.

In conclusion, this short communication has emphasized that the well known radiographic features of juvenile chronic arthritis are by no means pathognomonic of this entity. A large differential diagnosis must be considered, including haemophilia, idiopathic multicentric osteolysis, the mucopolysaccharidoses, a variety of skeletal dysplasias, infection, and synovial haemangioma. Correlation of radiographic observations with clinical findings will permit the establishment of an accurate and specific diagnosis in most instances, underscoring the need for close communication between the paediatric radiologist and practising paediatrician.
