Diseases Symptoms Signs Diagosis
Lab tests Imaging
Bronchiolitis
  • No specific lab findings
  • Viral tests like ELISA and immunoassays may be done in case of RSV infection.
  • Pulmonary function test is performed to exclude other lung diseases.
 No specific imaging findings.
Asthma
  • Lab tests are not specific for asthma but they are performed to exclude other diseases.
  • Serum examination shows elevated level of esoinophils due to allergy.
 CT scan shows dilated bronchi, bronchial wall thickening and air trapping.[1]
COPD
Bacterial pneumonia
Pulmonary embolism
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia
Influenza
Common cold
Tuberculosis
Interstitial pneumonitis (Hamman - Rich syndrome)
Foreign body aspiration
Sarcoidosis
Pertussis
  • Nasopharyngeal swab
  • Culture
  • Serology to detect pertussis toxin.
 No remarkable imaging findings.

Differential diagnosis of bronchiolitis: Asthma, COPD, sarcoidosis, pneumonia, heart failure, DIPNECH, foreign body inhalation, pulmonary embolism and GERD (in case it is associated with asthma).
