X-ray evaluation of an autosomal dominant osteopetrosis type 2 (ADO-2) phenotype. A AP skull radiograph showing generalized increase in bone density. B Sclerosis in the iliac wings, acetabuli and femoral heads. C Lateral thoracic and lumbar spine radiograph with dense sclerotic bands at the vertebral body endplates (‘sandwich vertebrae’). D AP phalanges radiograph with endobone (‘bone-in-bone’) appearance. E A full-length standing anteroposterior radiograph of both lower limbs showing diffused bone sclerosis, ‘Erlenmeyer flask’ deformity, and ‘bone-in-bone’ appearance. AP = anterior–posterior
