Chest X-rays:
Children with a clear clinical diagnosis of bronchiolitis do not require a chest x-ray.
CXR in bronchiolitis will show signs of hyperinflation, peribronchial thickening, and often patchy
areas of consolidation and collapse. This may lead to some confusion with pneumonia, however if
hyperinflation and wheeze are present the diagnosis should be regarded as bronchiolitis. The
aetiology of pneumonia in this age group is predominantly viral.
• A CXR should be done if complications are suspected e.g. Pleural effusion or extraneous air.
• A CXR is indicated in severe cases or where the diagnosis uncertain.
