Intrathoracic Schwannoma Presented with Hemothorax

Intrathoracic schwannomas are typically benign and asymptomatic tumors that originate from the Schwann cells of a neural sheath. Hemorrhage from intrathoracic schwannomas is an uncommon finding. We present the case of a 17 year-old girl who had dyspnea and numbness of the right arm. Chest x%u2013ray showed a right-sided massive pleural effusion and exploratory puncture showed hemothorax. After tube thoracostomy and drainage of the bloody effusion, a mass was observed in the right upper hemithorax. Chest tomography revealed a 76x104 mm mass arising from the fourth intercostal nerve. The tumor was successfully resected and, on histopathologic examination it was reported as a schwannoma. After resection, the patient has remained problem-free for fourteen months
