Which radiodensity is described as an ill-defined radiodensity on chest imaging?

• A. Consolidation
• B. Infiltrate
• C. Hyperlucency
• D. Opaque

Answer: (B)

Ill-defined radiodensity on chest imaging is described as an infiltrate. It signifies a hazy, poorly bordered area of increased density that lacks the sharp margins you’d expect with true consolidation. Consolidation is a denser, more uniform opacity with relatively clear borders and often air bronchograms, reflecting alveolar filling. Hyperlucency refers to areas that are more radiolucent (less dense) than normal, which is the opposite of an ill-defined opacity. Opaque describes a dense area but doesn’t specifically imply the indistinct margins typical of an infiltrate. So the term infiltrate best captures the idea of an ill-defined, hazy increase in radiodensity.
