The most common findings on chest radiographs in patients with ILDs are widespread nodular and/or fine linear (reticular) shadowing and/or ground-glass opacities. As noted, HRCT usually confirms the diagnosis, and the fibrosis score can help determine prognosis.
Honeycombing is usually a late finding, which carries a poor prognosis.
The presence of nodules may be indicative of hypersensitivity pneumonitis, granulomatous disease, pulmonary Langerhans cell histiocytosis, and respiratory bronchiolitis interstitial lung disease.
