Figure 7

38-year-old woman with cutaneous and pulmonary sarcoidosis complaining of a slight exertional dyspnea. Photograph of volar forearms shows red-to-purple indurated plaques. Biopsy demonstrated cutaneous sarcoidosis (Lupus Pernio) (a). Coronally-reformatted inspiratory CT image with soft tissue window settings, obtained two weeks after cutaneous biopsy, demonstrates mediastinal lymphoadenopathies (N) (b). Coronally-reformatted inspiratory CT image with lung settings through the same level of (b) shows absence of lung abnormalities (c). Extensive air-trapping can be seen on coronally-reformatted expiratory CT image (d). Coronally-reformatted inspiratory CT image, obtained six months after, shows typical sarcoidosis lung pattern (multiple micronodules with a perilymphatic distribution both in lower and upper lobes) (e).
