Massive intrathoracic bleeding caused by rupture of a benign schwannoma is extremely rare. A 73-year-old man was admitted to our emergency department because of chest pain and dyspnea. Computed tomography revealed massive pleural effusion and a posterior mediastinal tumor. Chest tube thoracostomy was performed, and the initial blood drainage was 1700 mL. Magnetic resonance imaging revealed that the tumor at the 8th costal level measured 46 × 60 mm. The tumor, located beside the 8th vertebra, had ruptured and caused the bleeding. It was successfully excised by thoracoscopic surgery and diagnosed as a benign schwannoma.
良性神经鞘瘤破裂导致大量胸腔内出血极为罕见。一名73岁男性因胸痛和呼吸困难入住我院急诊科。计算机断层扫描显示大量胸腔积液和后纵隔肿瘤。进行了胸腔闭式引流术，初始引流出的血液为1700毫升。磁共振成像显示第8肋水平的肿瘤大小为46×60毫米。位于第8胸椎旁的肿瘤已破裂并导致出血。通过胸腔镜手术成功切除该肿瘤，诊断为良性神经鞘瘤。
