Here, we report a case of haemangioma on middle mediastinum accompanied by unilateral pleural effusion, which was initially suspected to be lung cancer and pleurisy. During annual check-up, chest radiography of a 30-year-old female showed homogeneous opacity in the left lower pulmonary field. Excision was performed, and the mass was pathologically diagnosed as benign mediastinal vascular tumour with exudative pleural effusion. To our knowledge, this presentation occurs in <0.5% of tumours of the mediastinum, and furthermore, the presence of pleural fluid is extremely rare, and the underlying mechanism is unknown. Although mediastinal haemangioma is hard to diagnose without surgery, we should include it in the differential diagnosis of a tumour with unilateral pleural effusion.
在此，我们报告一例中纵隔血管瘤伴单侧胸腔积液的病例，该病例最初被怀疑为肺癌和胸膜炎。在年度体检期间，一名30岁女性的胸部X线检查显示左下肺野均匀性模糊。进行了切除手术，病理诊断该肿块为伴有渗出性胸腔积液的良性纵隔血管肿瘤。据我们所知，这种表现见于不到0.5%的纵隔肿瘤，此外，胸腔积液的存在极为罕见，其潜在机制尚不清楚。虽然纵隔血管瘤在未经手术的情况下难以诊断，但我们应将其纳入单侧胸腔积液肿瘤的鉴别诊断中。
