Early Mycoplasma pneumoniae infection presenting as multiple pulmonary masses: an unusual presentation in a child

Area of Science:

• Pediatric Pulmonology
• Infectious Diseases
• Radiology

Background:

• Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in children.
• Early imaging findings of pediatric Mycoplasma pneumonia are not well-documented due to limited pre-symptomatic imaging.
• Understanding early presentations is crucial for timely diagnosis and management.

Observation:

• An 11-year-old boy underwent spine MRI for scoliosis, incidentally revealing large pulmonary masses.
• These masses were asymptomatic at the time of initial detection.
• Eight days later, the patient developed acute respiratory symptoms.

Findings:

• The previously observed pulmonary masses transformed into diffuse bronchiolitis.
• Diagnostic tests confirmed Mycoplasma pneumoniae as the causative agent.
• This case presents an unusual subclinical imaging manifestation of Mycoplasma pneumonia.

Implications:

• This case expands the known spectrum of imaging findings for pediatric Mycoplasma pneumoniae infections.
• It emphasizes the importance of considering atypical presentations in pediatric respiratory illness.
• Further research into subclinical imaging findings could improve early detection of Mycoplasma pneumonia.
