[CT of gold pneumonitis]

We experienced five cases of gold pneumonitis. CT findings of four cases and pathological findings of an autopsy case were discussed. CT findings of gold pneumonitis could be classified as follow; (1) high density shadow of subpleural zone-BOOP suspected- (2) high density shadow along the broncho-vascular bundle (3) small cystic shadow of subpleural zone-UIP. Histological findings of an autopsy case revealed the fibrosis along the broncho-vascular bandle. A variety of radiologic and pathologic feature on the gold pneumonitis were seen.
