Figure 3: (a) CT scout (AP) view demonstrates a solitary cavitating nodule posteriorly within the right lower lobe (white arrow). The level of the first axial image from the CT colon study is shown by the red line, demonstrating that the scan commenced below the level of the lesion. (b) A selected image from the chest component of the subsequent CT examination demonstrates a cavitating soft tissue attenuation nodule within the posterior basal segment of the right lower lobe (black arrowhead).
