[Acute neonatal osteomyelitis, an incidental life-changing diagnosis]

Area of Science:

• Neonatal medicine
• Pediatric infectious diseases
• Skeletal infections

Background:

• Acute neonatal osteomyelitis is a severe infection posing diagnostic challenges, particularly in premature infants due to subtle clinical signs.
• Staphylococcus aureus is the predominant pathogen, with prematurity-related factors like invasive monitoring and prolonged catheterization increasing risk.
• Early and accurate diagnosis is vital to mitigate long-term comorbidities and developmental issues.

Observation:

• A case of osteomyelitis secondary to Staphylococcus aureus sepsis in a preterm infant (25 weeks 3 days gestation) is presented.
• The diagnosis was incidentally made through an abdominal X-ray, underscoring the often-paucisymptomatic presentation in neonates.
• Low parental compliance for follow-up impacts long-term outcome assessment, despite favorable indicators at 8 months.

Findings:

• Neonatal osteomyelitis, especially in preterm infants, presents with non-specific symptoms, complicating early detection.
• Incidental radiographic findings can be key to diagnosing this condition in vulnerable neonates.
• While early treatment is critical, long-term sequelae in preterm infants require ongoing monitoring.

Implications:

• Emphasizes the need for heightened clinical suspicion and advanced diagnostic imaging for osteomyelitis in preterm neonates.
• Highlights the importance of addressing risk factors associated with prematurity to prevent invasive bacterial infections.
• Stresses the necessity of consistent follow-up care to monitor developmental outcomes and manage potential sequelae in affected infants.
