Description

Radiologists use many terms to describe areas of decreased density or lucencies within the lung, like cyst, cavity, pneumatocele, emphysema, bulla, honeycombing, bleb etc.

Many of these terms are based on the pathogenesis of the abnormality.

This makes it difficult to use these terms, since in many cases when we describe a chest X-ray, we are trying to figger out what the pathology could be.

A more practical approach is to describe areas of decreased density in the lung as:

Cavity - lucency with a thick wall

Cyst - lucency with a thin wall

Emphysema - lucency without a visible wall
