Figure 4.

Nontranslobar lung consolidation. Longitudinal scan at the PLAPS point. No lung line is present, i.e. there is no pleural effusion. A tissue-like image with a mostly fractal, deep boundary with the aerated underlying lung, the shred sign (or fractal sign), makes the diagnosis of a nontranslobar lung consolidation (which is, of course, subpleural). This is an example of PLAPS. If found anteriorly, this would be an example of the C-profile. Black arrows: fractal line. White arrows: ribs.
