본문내용
Radiologic Findings of Idiopathic Interstitial Pneumonia
ATS/ERS Consensus
International standard
: Diagnostic criteria & terminology
7 clinico-radiologic-pathologic entities
Term of “pattern”
: Histopathologic diagnosis
Roles of HRCT
Separate pts with typical IPF/UIP
Detecting clues to non-IIP dz
Selecting appropriate site for biopsy
Follow-up
Idiopathic Pulmonary Fibrosis
Introduction
Chronic fibrosing interstitial pneumonia
Histologic pattern of UIP
Exclusion of other known causes of ILD
Clinical Features
Age of onset > usually 50 yrs
Gradual symptom of dyspnea
PFT : restrictive, DLCo↓
Median survival : 2.5-3.5 yrs
BALF : total cell count, neutrophils↑
Histologic Features
Temporal & spatial heterogeneity
Peripheral subpleural involvement
Radiologic features (CXR)
Reticular opacities
Honeycombing
Peripheral & basal
Volume loss
