A novel
mutation in TNFRSF11A gene causes pediatric osteopetrosis: case report. a–c The structure of limb bones is deformed. Extreme metaphyseal flaring, reduced bone vascularity and dense bone structure is found. d Skull radiograph showing typical wolf carnival appearance. e, f Front-Lateral Chest radiograph showing diffuse sclerotic vertebra and costochondral junction widening
Osteopetrosis.
ADO: Radiograph of left femur, age 4 years. Note Erlenmeyer flask deformity of distal femur (arrows) and generalised increased bone density.
Preschooler
with short stature. AP radiograph of the hand shows diffuse shortening of the phalanges and metacarpals, giving the hand the appearance of a trident. There is also metaphyseal flaring of the distal radius and ulna.The diagnosis was achondroplasia.
Preschooler
with short stature. AP radiograph of the lower extremities shows bilateral rhizomelic shortening of the femora and flaring of the distal femora and proximal and distal tibiae and fibulae.The diagnosis was achondroplasia.
