Overview

Bronchiolitis must be differentiated from other respiratory and cardiac diseases that are presented with similar clinical manifestations. Based on cough and dyspnea, bronchiolitis is differentiated from asthma, COPD, pneumonia, congestive heart failure, diffuse idiopathic neuroendocrine cell hyperplasia, tuberculosis, pertussis, foreign body aspiration, pulmonary embolism and Harmann-Rich syndrome.

Differentiating bronchiolitis from other diseases

Bronchiolitis must be differentiated from other respiratory and cardiac diseases that can cause the same clinical manifestations like cough and dyspnea. These diseases include asthma, COPD, pneumonia, congestive heart failure, diffuse idiopathic neuroendocrine cell hyperplasia, tuberculosis, pertussis, foreign body aspiration, pulmonary embolism and Harmann-Rich syndrome.[1][2][3][4][5]

Diseases Symptoms Signs Diagosis
Fever Cough Chest pain Wheezes Crackles Tachycardia Lab tests Imaging
Bronchiolitis +/- Dry - + + +/-
Asthma - Dry/Productive - + - -
  • Lab tests to exclude other diseases
  • Serum examination shows elevated level of esoinophils due to allergy
  • CT scan shows
    • Dilated bronchi
    • Bronchial wall thickening
    • Air trapping
COPD + Productive - + + +
Bacterial pneumonia + Productive + + + +/-
Pulmonary embolism +/- Bloody + + + +
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia[9] - Dry - + - -
  • Pulmonary function test shows obstructive lung disease
Tuberculosis + Bloody + - - -
  • Sputum culture:
    • Three successive positive culture for M. tuberculosis confirms the diagnosis[10]
    • Presence of acid fast bacilli in sputum smear indicates high extent tuberculosis
  • CT scan may show:[12]
  • EKG may have abnormalities in case pleural effussion associated with TB.
Interstitial pneumonitis (Hamman - Rich syndrome) + Productive - - + -
Foreign body aspiration + Bloody + + - -
  • Chest X ray shows
Pertussis + Dry - - -
  • No remarkable imaging findings
Congestive heart failure - Dry/Productive + while walking - - +
  • EKG to detect underlying cause
  • Chest x ray shows cardiomegaly
  • Echocardiography is done:
