Subpulmonic pleural effusion

Case contributed by Dr Ian Bickle


Right sided pleurtic chest pain and mild shortness of breath.

Patient Data

Age: 40 years
Gender: Female

Apparent elevation of the right hemidiaphragm.

The right base 'through the breast' is dense - note the difference to the normal left side if observing through the breast as it hangs below the diaphragm.

Case Discussion

A subpulmonic effusion is a pleural effusion that is only visualized in the erect projection. Rather than layering laterally and blunting of the costophrenic fluid, it lies almost exclusively between the lung base and the diaphragm, giving the impression of an elevated diaphragm and density behind it.
