Findings:
Inspiratory images show the normal tracheal morphology, with a
tracheal index of approximately 1. The bronchi and the pulmonary parenchyma appear normal in this phase with no consolidation.
The expiratory images show mildly exaggerated bowing of the posterior membrane with preserved integrity of the tracheal cartilage and close to 70% expiratory collapse. Minimal ground-glass opacities are seen on the expiratory images.
No pulmonary nodules, no emphysematous or fibrotic changes. No pleural effusion.
The heart, great vessels, and oesophagus have a normal appearance. There is no lymphadenopathy.
Small foci of calcification are noted throughout the pancreas, suggestive of chronic pancreatitis. The upper abdominal organs are otherwise unremarkable.
No bony abnormality is identified.
Impression:
Possible mild case of EDAC with approximately 70% expiratory tracheal collapse.
No interstitial lung disease, no acute inflammation.
