Abstract

PURPOSE
To describe HRCT findings in five patients with pathologically proved acute interstitial pneumonia
MATERIALS AND METHODS
This study included 5 patients with pathological and clinical diagnosis of acute interstitial pneumonia. Mean age of the patients was 40(range, 31-53 years). CT scans were reviewed by two chest radiologists retrospectively. CT scans were assessed for the presence and distribution of ground-glass attenuation, air-space consolidation, interlobular septal thickening, honeycombing, and pleural effusion.
RESULTS
The area of ground-glass attenuation and air-space consolidation were seen at HRCT in all 5 patients. These lesions were distributed diffusely in both lungs, but involved predominantly subpleural lungs in 2 patients and posterior lungs in 3 patients. Three patients had mild interlobular septal thickening. None of them showed honeycombing. Three of the 5 patients died within 52 days of initial manifestation.
CONCLUSION
Acute interstitial pneumonia differs from the more chronic form of idiopathic interstitial pneumonia in their HRCT findings.
