A 58-year-old man was admitted to our hospital because of dyspnea, dysphagia, and back pain. A chest roentgenogram showed bilateral pleural effusion. Bloody fluid was aspirated via thoracocentesis, but no malignancy was detected on cytological examination. Computed tomography revealed a hypodense circular mass approximately 8 cm in diameter with well-defined margins in the posterior mediastinum. Furthermore, T2-weighted magnetic resonance imaging showed the lesion to be a hyperintense mass. Video-assisted thoracoscopic surgery was performed, and the tumor was diagnosed as a mediastinal cystic hemangioma. The bilateral bloody pleural effusion was attributed to the cystic tumor.
一名58岁男性因呼吸困难、吞咽困难和背痛入院。胸部X线片显示双侧胸腔积液。通过胸腔穿刺抽出了血性液体，但细胞学检查未发现恶性肿瘤。计算机断层扫描显示后纵隔有一个直径约8厘米的低密度圆形肿块，边界清晰。此外，T2加权磁共振成像显示该病变为高信号肿块。进行了电视辅助胸腔镜手术，肿瘤被诊断为纵隔囊性血管瘤。双侧血性胸腔积液归因于囊性肿瘤。
