How should small pleural effusions be described on chest radiographs?

• A. Describe presence and estimated amount (small, moderate), laterality, and correlate with symptoms; suggest follow-up if clinically indicated.
• B. Describe only the presence of effusion without size estimation.
• C. Note that effusion is large in all cases.
• D. Suggest no follow-up regardless of symptoms.

Answer: (C)

When a small pleural effusion is seen on chest radiographs, report should document its presence and estimate the amount (even if small), specify the side(s) involved, and note whether symptoms correlate with the finding. If clinically indicated, suggest follow-up imaging or clinical reassessment. This approach matters because radiographs can underestimate effusions, and a size estimate helps guide management and future imaging decisions. Merely stating that an effusion is present without size estimation leaves the clinical team without a sense of its extent. Saying the effusion is large in all cases is inaccurate for small effusions, and recommending no follow-up regardless of symptoms risks missing progression or an underlying process.
