Insights
Kingella kingae commonly causes bone and joint infections in young children. This case highlights a rare instance of this bacterium presenting as a chest mass, mimicking a tumor in an infant.
Area of Science:
- Pediatric infectious diseases
- Bacterial pathogenesis
- Medical imaging and diagnostics
Background:
- Kingella kingae is a known cause of osteoarticular infections in children under five.
- Recent literature indicates an increase in unusual clinical presentations of Kingella kingae infections.
- Early and accurate diagnosis is crucial for effective management of pediatric infections.
Observation:
- A rare case of a chest mass was observed in an 11-month-old infant.
- The clinical presentation of the chest mass mimicked a neoplastic tumor.
- Diagnostic investigations were performed to determine the etiology of the mass.
Findings:
- The chest mass was confirmed to be caused by Kingella kingae infection.
- This represents an unusual manifestation of Kingella kingae, distinct from typical osteoarticular sites.
- Microbiological and imaging data supported the diagnosis.
Implications:
- This case expands the spectrum of clinical manifestations associated with Kingella kingae.
- It underscores the importance of considering infectious etiologies, including Kingella kingae, in pediatric chest masses.
- Enhanced awareness among clinicians may improve diagnostic accuracy and patient outcomes for rare presentations.
Abstract:
Kingella kingae has been recognized as a common etiology of pediatric osteoarticular infections, especially among children younger than 5 years of age. In recent years, there have been reported cases of unusual manifestations. We report a rare case of a chest mass mimicking a tumor in an 11-month-old baby.
