= VOORHOEVE DISEASE

= disorder of secondary spongiosa of X-linked dominant inheritance / sporadic occurrence

• usually asymptomatic (similar to osteopoikilosis)
• NO known associated physical / laboratory abnormality → incidental radiographic discovery

Genetics: unknown

Location: all long bones symmetrically affected

Site: the only bone sclerosis primarily involving metaphysis (with extension into epi- and diaphysis)

• dense linear longitudinal striations in diaphyses + metaphysis of long tubular bones: typically in areas of rapid growth
• radiating fan-shaped densities of “sunburst” appearance from acetabulum into ileum
