Spectrum of lung toxicities caused by Rituximab. a Axial CT images of the chest acquired during arterial phase in a 48-year-old female patient with CLL on maintenance therapy with Rituximab show bilateral ground glass opacities more prominent in the left lower lobe suggestive of drug induced pneumonitis. b Axial CT images of the chest in an 84 year old female patient with CLL on Rituximab therapy shows bilateral, symmetric homogenous ground glass opacities in both the lungs consistent with hypersensitivity pneumonitis c Axial CT images of the chest obtained during arterial phase in a 45 year old male patient with CLL on maintenance with Rituximab shows hypoattenuated lungs with peribronchial thickening suggestive of bronchiolitis obliterans (thin white arrows)
