Detection of incidental schwannoma by traumatic hemothorax

A case of hemothorax caused by traumatic rupture of schwannoma is rarely reported. We present a case of thorax injury of an 18-year-old woman who had fallen from a high place with a Glasgow Coma Score 13. Chest X-ray showed a left-sided massive pleural effusion. Chest tomography revealed a 105×80 mm formation in the left lung basal region. The patient underwent an emergency thoracotomy after 2000 cc blood drainage with intercostal tube placement. Tumor’s pathologic diagnosis was schwannoma (neurilemmoma). In this case study, we would like to present a traumatic hemothorax for the previously unknown mediastinal mass with the relevant literature.
