Pleural Dissemination of Lung Cancer: CT Diagnosis / 日本農村医学会雑誌

ABSTRACT

Pleural dissemination of a tumor is one form of the extrapleural involvments of lung cancer. CT images of pathologically proved pleural dissemination of lung cancer in 18 patient were included in this study. CT features of (a) small nodular opacities in the interlobar area and/or thickening of interlobar fissure, and (b) irregular pleural surface of the chest wall were retrospectively reviewed. Fourteen of 18 cases (78%) showed interlobar abnormalities and nine cases (50%) demonstrated irregular pleural surface of the chest wall. We concluded that CT scanning could play an important role in the clinical diagnosis of pleural dissemination of lung cancer.
