Twenty three-year-old man had thoracal spinal cord surgery for gunshot injury three months ago. He had right hemiplegia and paraplegia for the past two months. He was admitted with poor performance status and progressive, severe dyspnea. Chest X-ray showed massive pleural effusion on the right side. Thoracentesis showed transudative pleural fluid. Duropleural fistula was considered due to the history of spinal injury and surgery. The presence of cerebrospinal fluid in the pleural fluid was demonstrated by beta-2 transferrin test. After the demonstration of the presence of duropleural fistula on intrathecal contrast-enhanced computed tomography scan surgical management of the duropleural fistula was successfully repaired by duroplasty. This case was presented as a complication of spinal cord injury and neurosurgery duropleural fistula is a very rare reason of massive transudative pleural effusions and the use of the cerebrospinal fluid by beta-2 transferrin in pleural effusion is reported very rare in the literature.
