Inflammatory myositis-associated interstitial lung disease can be distinguished from that associated with other connective tissue diseases.

Background: Acute onset of interstitial lung disease (ILD) has been described in patients with idiopathic inflammatory myositis (IIM), but controlled studies about this issue are sparse. The aim of this study was to compare disease onset, demographics, and high-resolution computed tomography (HRCT) patterns in IIM-ILD and other connective tissue disease (CTD)-ILDs.

Methods: Clinical and radiological data of 22 IIM-ILD and 132 other CTD-ILD patients was retrospectively gathered from hospital registries between January 2000 and November 2019.

Several specific high-resolution computed tomography patterns correlate with survival in patients with idiopathic pulmonary fibrosis.

Background: Evidence of honeycombing in high-resolution computed tomography (HRCT) is a recognized risk factor for shortened survival in patients with idiopathic pulmonary fibrosis (IPF), but few studies have evaluated the feasibility of exploiting other specific patterns for predicting survival. The aim of this study was to examine the extent of specific HRCT patterns in IPF and determine whether they correlate with clinical features, pulmonary function tests (PFT), and survival.

Methods: Both the presence and extent of specific HRCT patterns, such as traction bronchiectasis, honeycombing, architectural distortion, reticulation, emphysema, and ground glass opacity, in 129 HRCT examinations were scored semi-quantitatively in three zones of each lung.

Several high-resolution computed tomography findings associate with survival and clinical features in rheumatoid arthritis-associated interstitial lung disease.

Objective: To compare the presence and extent of several high-resolution computed tomography (HRCT) observations in different subtypes of rheumatoid arthritis-related interstitial lung disease (RA-ILD) and to examine associations between radiological findings, hospitalization, age, RA duration, pulmonary function tests (PFT) and survival.

Materials And Methods: HRCTs from 60 RA-ILD patients were independently evaluated and re-categorized into usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), organizing pneumonia (OP), diffuse alveolar damage (DAD) and unclassified subtypes by two radiologists. The presence and extent, which was reported using a semi-quantitative scoring system, of e.
