[A study on the problems of the radiologic manifestations in sarcoidosis].

Unilateral hilar adenopathy, which is considered as an atypical manifestation of sarcoidosis, appeared only on the initial stage, and eventually became bilateral. The adenopathy may occur in all groups of the mediastinal lymph nodes. The roentgenological findings of the pulmonary parenchymal lesions include interstitial, alveolar, miliary and fibrous lesions. The alveolar involvement, and the pathological consideration of pseudoalveolar manifestations in X-ray film were discussed.
