Laboratory Studies
- Although no specific laboratory tests exist to diagnose infantile cortical hyperostosis, laboratory studies may be performed to help exclude other diagnoses.
- Erythrocyte sedimentation rate (ESR) and alkaline phosphatase levels are often elevated.
- Anemia and leukocytosis may be present.
Imaging Studies
- Radiography is the most valuable diagnostic study in infantile cortical hyperostosis. Radiographs show layers of periosteal new bone formation, with cortical thickening in variable combinations of the long bones, mandible, and clavicle. Initially, periosteal new bone is observed to engulf the diaphysis of the bone, causing an increase in diameter of the bone. Soft-tissue swelling is evident as well. Over time, the periosteal new bone density increases, becoming homogeneous with the underlying cortex. Eventually, the bone remodels and resumes a normal appearance.
- Other diagnostic imaging studies have not proved to be helpful. Magnetic resonance imaging (MRI) results have been described but do not add any significant information to that of radiographs.
- Ultrasonography may be used to diagnose prenatal cases. The appearance of infantile cortical hyperostosis on sonograms is similar to that of cases of osteogenesis imperfecta.
Histologic Findings
In the early stages of infantile cortical hyperostosis, inflammation of the periosteum and adjacent soft tissues is observed. As this resolves, the periosteum remains thickened and subperiosteal immature lamellar bone is observed. The bone marrow spaces contain vascular fibrous tissue. Mature specimens show hyperplasia of lamellar cortical bone without inflammation or subperiosteal changes.
