Pneumonitis associated with nivolumab therapy in a 61-year-old woman with metastatic clear cell RCC. The patient presented in the emergency department with shortness of breath 1 month after the initiation of nivolumab therapy. (a) Axial CT image of the chest shows patchy peribronchovascular consolidation, which is most pronounced in the right lower and middle lobes (red arrows). The nivolumab therapy subsequently was stopped, and the patient was given corticosteroids. Black arrow = right middle lobe metastasis. (b) Axial CT image of the chest obtained 1 month later shows near-complete resolution of consolidation. Arrow = right middle lobe metastasis.
