On the left a patient who is treated with cytotoxic drugs for a hematologic malignancy. The radiographic findings are areas of ground glass opacity, some traction bronchiectasis and subtle honeycombing in the left lower lobe. This could be the result of an idiopathic form of fibrosis like idiopathic pulmonary fibrosis and non-specific interstitial pneumonitis or fibrosis in chronic hypersensitivity pneumonitis and longstanding sarcoid. However it is not one of the typical forms of fibrosis, that we commonly encounter in patients with a UIP pattern or NSIP pattern seen in collagenvascular diseases. When there is fibrosis, that does not fit into any of the common diseases with fibrosis always consider drug-related lung disease in the differential. #Clinical #Radiology #CTChest #DrugInduced #DrugRelated #Fibrosis #RadiologyAssistant
