The morphologic domain comprises features from 3 categories: (1) high-resolution computed tomography imaging patterns commonly found in patients with CTD-ILD, such as those with NSIP, organizing pneumonia, NSIP with organizing pneumonia, and lymphoid interstitial pneumonia; (2) histopathologic findings in an SLB that are highly associated with the presence of CTD, such as an NSIP pattern, organizing pneumonia pattern, lymphoid interstitial pneumonia pattern, the presence of interstitial lymphoid aggregates with germinal centers, and diffuse lymphoplasmacytic infiltration with or without lymphoid follicles; and (3) multicompartment involvement, which includes additional features evident on diagnostic imaging, histopathology, cardiac catheterization, or pulmonary function testing.
