  		Figure 5. (a) Three-dimensional CT of the right lung base obtained from a healthy subject showed smooth surfaces except for the interlobar fissure and the region surrounding the inferior vena cava. (b) Three-dimensional CT of the right lung base obtained from an aurora sign-positive patient showed marked irregularity or cobble stone appearance of the lung surface.
