ABSTRACT
Sarcoidosis is a systemic granulomatous disease of unknown etiology. Although refractory sarcoidosis has not been exactly defined, we would like to define it as a chronic uncontrolled progressive fibrotic condition resulting from various factors. Typical radiographic findings of pulmonary sarcoidosis are multiple small nodules with perilymphatic distribution. Fibrosis around bronchovascular bundles and interlobular interstitial fibrosis frequently occur in disease progression. Radiography of refractory sarcoidosis is presented and explained.
