Caffey's Disease (Infantile Cortical Hyperostosis)
Conservative management with symptomatic relief using NSAIDs (ibuprofen) and analgesics (paracetamol) is the recommended approach for Caffey's disease, as this self-limiting condition resolves spontaneously within 3-6 months without requiring aggressive interventions.
Clinical Recognition
Caffey's disease presents as acute periosteal inflammation with cortical hyperostosis and soft tissue swelling in infants, typically under 6 months of age. Key clinical features include:
- Bony-hard swelling over affected bones (mandible, clavicle, ribs, long bones)
- Hyperirritability and excessive crying due to pain
- Fever (may be present)
- Limited movement of affected limbs
- Elevated inflammatory markers (ESR, CRP) and alkaline phosphatase
The condition often appears 10-14 days post-immunization or presents from birth 1, 2, 3.
Diagnostic Approach
Radiographic findings are pathognomonic:
- Cortical thickening with subperiosteal new bone formation
- "Cotton-wool" appearance in severe prenatal cases
- Anterior cortex involvement most prominent 2
Laboratory findings:
- Elevated alkaline phosphatase
- Elevated inflammatory markers (ESR, CRP)
- Normal calcium and phosphorus
Biopsy confirmation may be performed when diagnosis is uncertain, but typical clinical-radiological correlation often suffices 1.
Critical Differential Diagnoses to Exclude
Before confirming Caffey's disease, rule out:
- Osteomyelitis (infection markers, fever pattern, bone scan)
- Malignancy (neuroblastoma, leukemia)
- Osteogenesis imperfecta (fracture history, genetic testing)
- Congenital infection (TORCH screening)
- Non-accidental injury (skeletal survey, social assessment)
Management Protocol
Primary Treatment
NSAIDs are first-line therapy:
- Ibuprofen for anti-inflammatory effect and pain control
- Paracetamol for additional analgesia
- Duration: Continue until symptoms resolve (typically 2-6 weeks) 3
Monitoring Schedule
- Weekly clinical assessment during acute phase
- Serial radiographs every 4-6 weeks to document resolution
- Complete resolution expected within 3 months, though severe prenatal cases may take up to 2 years 1, 4
What NOT to Do
- Avoid antibiotics unless concurrent infection confirmed
- Avoid surgical intervention for swelling (unnecessary and potentially harmful)
- Avoid corticosteroids (no evidence of benefit in Caffey's disease, unlike osteopetrosis where they have limited second-line role)
- Avoid biopsy if clinical-radiological features are classic
Prognosis and Counseling
Reassure parents firmly:
- This is a self-limiting condition with excellent prognosis
- Complete spontaneous resolution occurs in all cases
- No long-term functional impairment in most cases
- Residual mandibular asymmetry may persist but rarely requires surgical correction 5, 6
Special Considerations
Prenatal/Severe Cases
Prenatal Caffey's disease (diagnosed in utero) carries higher mortality risk due to:
- Pulmonary hypoplasia from rib involvement
- Hepatic dysfunction
- Hydrops fetalis 4
However, survivors show complete radiographic resolution by age 2 years with normal growth and development 4.
Dental Implications
Children with residual mandibular enlargement may develop:
- Feeding difficulties
- Increased caries risk
- Need for multidisciplinary dental management 6
Key Clinical Pitfall
The most common error is misdiagnosing Caffey's disease as osteomyelitis or malignancy, leading to unnecessary antibiotics, biopsies, or chemotherapy. The combination of typical age (under 6 months), characteristic radiographic cortical thickening, absence of systemic toxicity, and elevated alkaline phosphatase should prompt consideration of Caffey's disease first 1, 2, 3.
