Insights
Pediatric Mycoplasma pneumoniae pneumonia presents with fever and cough. Chest X-rays commonly show bilateral interstitial infiltrates, aiding diagnosis in children.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Radiology
Background:
- Mycoplasma pneumoniae pneumonia is a common cause of community-acquired pneumonia in children.
- Accurate diagnosis relies on clinical, serological, and radiological findings.
Purpose of the Study:
- To evaluate the clinical and chest radiographic features of pediatric patients diagnosed with Mycoplasma pneumoniae pneumonia.
Main Methods:
- Retrospective review of clinical records and chest radiographs.
- Inclusion of 39 pediatric patients (age 3-13 years) with confirmed Mycoplasma pneumoniae infection (IgG and IgM positive).
Main Results:
- Fever and cough were predominant symptoms (>90%).
- Chest radiography revealed diverse patterns, most commonly interstitial infiltrates (49%), followed by airspace consolidation (38%).
- Bilateral peribronchial/perivascular interstitial infiltrates were frequent (49%); pleural effusion (23%) and hilar lymphadenopathy (13%) were also observed.
Conclusions:
- Mycoplasma pneumoniae pneumonia in children exhibits varied radiological presentations.
- Bilateral peribronchial and perivascular interstitial infiltrates represent the most common radiographic finding.
Background:
The purpose of the present paper was to evaluate the clinical and chest radiographic features of pediatric patients with serologically proven Mycoplasma pneumoniae pneumonia (mycoplasma pneumonia).
Methods:
The clinical records and chest radiographs of 39 consecutive patients (19 male, 20 female; age 3-13 years) with serologically positive IgG and IgM mycoplasma pneumonia were reviewed.
Results:
More than 90% of patients presented with fever and cough and 48% of patients had leukocyte count >10,000/mm(3). A C-reactive protein (CRP) level >0.375 mg/dL was noted in 28 patients (72%). Chest radiographs displayed four different patterns: (i) peribronchial and perivascular interstitial infiltrates (n= 19, 49%); (ii) airspace consolidations (n= 15, 38%); (iii) reticulonodular opacification (n= 3, 8%); and (iv) nodular or mass-like opacification (n= 2, 5%). Bilateral peribronchial perivascular interstitial infiltrations in central and middle lung zones were frequently seen (n= 19, 49%). Other radiological features were bilateral lesions in 51% of patients, pleural effusion in 23%, and hilar lymphadenopathy in 13%. Means of duration for treatment response and hospitalization were 2.5 and 5 days, respectively.
Conclusion:
There are various radiological features of mycoplasma pneumonia in children. Bilateral peribronchial and perivascular interstitial infiltrates were most frequently seen in the present patients.
