Insights
Pediatric COVID-19 pneumonia typically presents mildly. Moderate cases show more cough and characteristic CT imaging findings, aiding early diagnosis and treatment.
Area of Science:
- Pediatric infectious diseases
- Pulmonology
- Radiology
Background:
- COVID-19 in children is generally mild, differing from adult presentations.
- Early diagnosis and treatment of pediatric COVID-19 pneumonia require understanding its features.
Purpose of the Study:
- To investigate the epidemic, clinical, and imaging characteristics of pediatric COVID-19 pneumonia.
- To aid in the early diagnosis and treatment of pediatric COVID-19 pneumonia.
Main Methods:
- Analysis of epidemic, clinical, and imaging data from 41 children with COVID-19.
- Categorization into mild and moderate severity groups.
Main Results:
- Mild cases (30 children) often asymptomatic or had low fever, cough, or fatigue. Moderate cases (11 children) had fever, cough, and runny nose, with significantly more cough (P<0.05).
- Pulmonary CT imaging revealed lesions in 11 moderate cases, including ground glass opacity (90.9%), consolidation (27.3%), and enlarged bronchovascular bundles (63.6%). Lesions were distributed along the bronchus and in various lung lobes.
- Enlarged pulmonary hilum lymph nodes were observed in 18.2% of moderate cases.
Conclusions:
- Pediatric COVID-19 pneumonia presents with mild to moderate clinical and imaging findings.
- Understanding clinical and CT imaging features is crucial for diagnosing cases with negative nucleic acid tests and reducing misdiagnosis of atypical presentations.
Background:
Pediatric COVID-19 is relatively mild and may vary from that in adults. This study was to investigate the epidemic, clinical, and imaging features of pediatric COVID-19 pneumonia for early diagnosis and treatment.
Methods:
Forty-one children infected with COVID-19 were analyzed in the epidemic, clinical and imaging data.
Results:
Among 30 children with mild COVID-19, seven had no symptoms, fifteen had low or mediate fever, and eight presented with cough, nasal congestion, diarrhea, headache, or fatigue. Among eleven children with moderate COVID-19, nine presented with low or mediate fever, accompanied with cough and runny nose, and two had no symptoms. Significantly (P < 0.05) more children had a greater rate of cough in moderate than in mild COVID-19. Thirty children with mild COVID-19 were negative in pulmonary CT imaging, whereas eleven children with moderate COVID-19 had pulmonary lesions, including ground glass opacity in ten (90.9%), patches of high density in six (54.5%), consolidation in three (27.3%), and enlarged bronchovascular bundles in seven (63.6%). The lesions were distributed along the bronchus in five patients (45.5%). The lymph nodes were enlarged in the pulmonary hilum in two patients (18.2%). The lesions were presented in the right upper lobe in two patients (18.1%), right middle lobe in one (9.1%), right lower lobe in six (54.5%), left upper lobe in five (45.5%), and left lower lobe in eight (72.7%).
Conclusions:
Children with COVID-19 have mild or moderate clinical and imaging presentations. A better understanding of the clinical and CT imaging helps ascertaining those with negative nucleic acid and reducing misdiagnosis rate for those with atypical and concealed symptoms.
