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.
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).
