Presentation
Progressive breathlessness over several weeks. Dull percussion note at the base.
- Homogeneous basal opacity with a concave, meniscus-shaped upper border rising laterally

- On the lateral view the fluid fills the posterior costophrenic recess
- The decubitus film shows fluid moving to the dependent side — the effusion is free-flowing
