Thoracic venous aneurysms are rare, and bleeding is possible. A 9-year-old female patient presented with a thoracic wall mass. No blood flow was observed in the mass, and a chronic expanding haematoma was suspected based on the differential diagnosis. However, the venous structure was identified in the wall of the mass on pathological examination, and the diagnosis of the venous aneurysm was thereby established. Because the venous aneurysm contains fresh blood and bleeding can be profuse when such lesions are not properly handled during a surgical procedure, making the visibility of the surgeon poor, the venous aneurysm must be included in the differential diagnosis.
胸段静脉瘤罕见，且有出血可能。一名9岁女性患者出现胸壁肿块。肿块内未观察到血流，根据鉴别诊断怀疑为慢性扩张性血肿。然而，病理检查在肿块壁中发现了静脉结构，从而确诊为静脉瘤。由于静脉瘤内含有新鲜血液，手术过程中若处理不当，此类病变可能大量出血，导致术野不清，因此静脉瘤必须列入鉴别诊断范围。
