Two forgotten signs in pneumothorax

The coin test is said to be characteristic and pathognomonic, and is performed by placing a coin flat upon the chest and striking it with another coin while the ear of the auscultator is placed at the back of the chest. The sound thus elicited is a peculiar metallic ringing or bell-like sound, not heard in any other condition.

Hippocratic succussion is also characteristic, and consists of shaking the patient while the ear is applied to the chest, when a splashing sound is heard.

Looking at apex in upright posture is more revealing then the rest of portions of chest

CT hardly ever misses even the smallest of pnumothorax
