(A) The patient developed finger clubbing which resolved during pregnancy. (B) A high‐resolution computed tomography (HRCT) of the chest reveals extensive, bilateral reticular nodular opacification, and associated wide‐spread ground glass with no significant zonal predominance. There are small islands of relative lucency consistent with mosaicism. (C) An open lung biopsy demonstrates a mild to moderate diffuse interstitial lymphocyte infiltrate with interstitial fibrosis devoid of spatial and temporal heterogeneity or architectural remodelling (haematoxylin and eosin (H&E): 40×), consistent with non‐specific interstitial pneumonia. (D) A follow‐up HRCT obtained two years later, after treatment with immunosuppression and danazol, demonstrates significant improvement.
