Case contributed by Assoc Prof Frank Gaillard

CT of the chest demonstrates a very large right sided pleural collection with thickened surrounding pleura (the so called split pleura sign) and multiple gas bubbles. The adjacent lung is compressed and collapsed.

The findings are consistent with an empyema.
