Unilobar re-expansion pulmonary oedema following removal of a large intra-thoracic mass.

Re-expansion pulmonary oedema (RPE) is not so rare complication associated with sudden expansion of a collapsed lung. RPE has been most frequently reported following rapid drainage of a large pneumothorax or chronic pleural effusion. Development of RPE following removal of a large intrathoracic mass is not commonly recognised, though sporadic reports exist in the literature. RPE can be fatal, but early diagnosis with appropriate management usually leads to satisfactory outcomes. We report a case of RPE, which occurred following removal of a giant intra-thoracic mass and its subsequent management and outcome with a brief review of relevant literature.
