What finding favors pneumothorax?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Pleural line without peripheral markings

In pneumothorax, air separates visceral from parietal pleura, producing a visible pleural line with absent lung markings beyond that line.

Option by option

  • A. Diffuse bilateral opacity

    Diffuse opacity may reflect edema, infection, or other processes.

  • B. Cardiomegaly

    Cardiomegaly is an enlarged cardiac silhouette.

  • C. Meniscus at base

    A basal meniscus suggests pleural effusion.

  • D. Pleural line without peripheral markings (correct)

    Correct: no markings beyond a pleural line supports pneumothorax.
