Sarcoid-like lymphadenopathy in an asymptomatic 81-year-old man with metastatic melanoma treated with ipilimumab. (Reprinted, with permission, from reference 43.) (a) Coronal reformatted contrast-enhanced chest CT scan obtained 4.9 months after the initiation of ipilimumab therapy shows new bilateral symmetric mediastinal and hilar lymphadenopathy (arrows) resembling sarcoidosis. (b) Axial CT image of the lungs shows bilateral irregular and nodular parenchymal opacities with upper- and middle-lung predominance (arrows) and peribronchovascular involvement, which falls in the spectrum of lung parenchymal manifestations of pulmonary sarcoidosis.
