Overview

Bronchiolitis must be differentiated from other respiratory and cardiac diseases that present with similar clinical manifestations of cough and dyspnea. Bronchiolitis should be differentiated from asthma, COPD, pneumonia, congestive heart failure, diffuse idiopathic neuroendocrine cell hyperplasia, tuberculosis, pertussis, foreign body aspiration, pulmonary embolism, and Harman-Rich syndrome.

Differentiating bronchiolitis from other diseases

Bronchiolitis must be differentiated from other respiratory and cardiac diseases that can cause the similar clinical manifestations like cough and dyspnea. The differentials include the follwoing:[1][2][3][4][5]

Diseases Symptoms Signs Diagosis
Fever Chest pain Cough Wheeze Crackles Tachycardia Lab tests Imaging
Bronchiolitis +/- - Dry + + +/-
Asthma - - Dry/Productive + - -
Chronic obstructive pulmonary disease (COPD) + - Productive + + +
Bacterial pneumonia + + Productive + + +/-
Pulmonary embolism (PE) +/- + Bloody + + +
Diffuse idiopathic neuroendocrine cell hyperplasia[9] - - Dry + - -
Tuberculosis + + Bloody - - -
Interstitial pneumonitis (Hamman - Rich syndrome) + - Productive - + -
Foreign body aspiration + + Bloody + - -
Pertussis + Dry - - -
  • No remarkable imaging findings
Congestive heart failure - + while walking Dry/Productive - - +
