Pulmonary parenchymal manifestations associated with ulcerative colitis (UC) include various conditions such as opportunistic infections, interstitial pneumonia, organizing pneumonia, and adverse drug reactions. We present a case of interstitial pneumonia associated with UC in a 61-year-old nonsmoking woman. High-resolution computed tomography demonstrated multifocal ill-defined areas of consolidation and ground-glass attenuation with or without traction bronchiectasis, predominantly in peripheral lung parenchyma. Lung biopsy showed that the closest pathologic pattern in the areas of abnormality was cellular and fibrotic nonspecific interstitial pneumonia. We also discuss the evaluation and treatment of pulmonary disease possibly related to UC in the clinical course of this patient.
