Juvenile idiopathic osteoporosis.

Juvenile idiopathic osteoporosis (JIO) is a very rare condition of primary bone demineralisation that presents in childhood. Most pediatricians are unfamiliar with this condition owing to the difficulty in recognition and a long list of differential diagnosis. We report an 8-year-old girl who presented with generalized severe osteoporosis. Diagnosis of JIO was made by excluding other common causes of osteoporosis in this age.
