title: Four faces of a parapneumonic effusion: pathophysiology and varied radiographic presentations.
abstract: We report a patient methicillin-resistant Staphylococcus aureus pneumonia who developed fluid collections in three spaces in the thorax, the pleural space, the pericardial space, and a pre-existing bulla, in addition to mediastinal oedema. We discuss the universal pathogenesis for the development of these fluid collections and the explanation for the most common presentation being a parapneumonic effusion.
