Fig. 4: Schematic illustration of pleura-associated nodules on CT.
From: Integrated predictive model for visceral pleural invasion in small NSCLC with high clinical utility
Representative images of the pleural-attached nodule (A, B), pleural-tag nodule (C, D) and nodule pushed against pleura (E, F). Different slice of the same nodule in CT image of a right lower lobe pleural-attached nodule with pleural indentation (A, B). The nodule surface directly touched the pleura surface. Axial CT (C, D) showed a right upper lobe pleural-tag nodule. There was one or more linear tag between the nodule and pleura, but the nodule does not directly touch the pleura. Axial CT (E) and coronal CT (F) showed a left lower lobe nodule pushed against the interlobar pleura.
