Overview

Physical Examination

  • Physical examination of a patient with cryptogenic organizing pneumonia demonstrates signs of bronchospasm, consolidation, and fluid accumulation.
  • The prevalence and severity of these findings depends on the extent of parenchymal involvement and the subtype of organizing pneumonia.[1]
Sign Cryptogenic Organizing Pneumonia Secondary Organizing Pneumonia Focal Organizing Pneumonia
Tachypnea 65% 70% -
Crackles 85% 95% 10%
Wheezing 10% 10% 10%
Clubbing - 5% -
Cyanosis 5% 5% -


Appearance of the Patient

  • Patients with cryptogenic organizing pneumonia usually appear in mild distress.[2]

Vital Signs

  • Low-grade fever
  • Tachycardia with regular pulse
  • Tachypnea
  • Normal blood pressure with normal pulse pressure

Skin

  • Skin examination of patients with cryptogenic organizing pneumonia is usually normal.

HEENT

  • HEENT examination of patients with cryptogenic organizing pneumonia is usually normal.

Neck

  • Neck examination of patients with cryptogenic organizing pneumonia is usually normal.

Lungs

  • On examination patient is in mild dyspnea
  • Lungs are hyperresonant
  • Fine/coarse crackles upon auscultation of the lung bases/apices bilaterally depending upon the consolidation.
  • Vesicular breath sounds
  • Wheezing may be present

Heart
