Examples of typical skeletal abnormalities in patients with inborn errors of metabolism. a. Erlenmeyer flask deformity in the distal femur of a patient with type 1 Gaucher disease (plain radiograph). b. Fragility fractures (arrows) in the femoral neck and diaphysis of a patient with X-linked hypophosphatemic rachitis (T2-MRI). c. Myelopathy (arrow) due to narrowing of the spinal canal in MPS-I. Note the platyspondylia (flattened vertebral bodies) as part of the dysostosis multiplex (T2-MRI). d. Avascular necrosis on the right side, normal femoral head on the left in a patient with Gaucher disease (plain radiograph)
