Objective: To evaluate the potential role of helical high resolution computed tomography (HHRCT) in assessment of pleural indentation (PI) associated with peripheral bronchogenic carcinoma.Materials and Methods:Sixty patients with peripheral bronchogenic carcinoma confirmed by pathology were collected in this series. The pleural indentation presented on HHRCT scans varied with the size and location of the lesion. The pathologic basis of pleural indrawing were briefly evaluated.Results:According to the location of the tumor, the findings of the PI could be divided as type A, having two or more lines extending to the visceral pleura and terminating in a small triangular density at the pleura; type B, typical PI; and type C, untapered straight or undulating lines of minor or major fissure.Conclusion: HHRCT, especially 3D reconstruction with surface shielding display, is helpful to show the pleural indentation in peripheral lung cancer.
