慢性结核性脓胸合并恶性肿瘤的影像诊断(附3例报告)

目的探讨慢性结核性脓胸合并恶性肿瘤的临床与影像学表现。方法对我院发现经病理证实的3例慢性结核性脓胸合并恶性肿瘤病例进行影像分析,并复习相关文献。结果胸片及CT均示患侧胸膜增厚、钙化,脓胸肺侧出现软组织肿块,肿块与脓胸壁连续移行,该处钙化影移位、散开、减少、中断,肿块密度较均匀(1例)或欠均匀(2例)。结论慢性结核性脓胸合并恶性肿瘤的影像表现有一定特征性,尤其钙化影改变、软组织块的出现及胸壁脂肪界面不清,更有诊断价值。

Imaging Diagnosis of Chronic Tuberculous Pyothorax Associated with Malignant Tumors: A Report of 3 Cases

Objective To study the clinical and imaging features of chronic tuberculous pyothorax associated with malignant tumors.Methods Imaging features of three cases of chronic tuberculous pyothorax associated with malignant tumors proved by pathology were analyzed with literatures reviewed.Results On chest radiograph and CT,thickening and calcification of the parietal and visceral pleura,soft tissue masses in the lung field adjacent to the empyema were showed.The soft tissue masses were connected with the wall of empyema,the density was homogeneous(one case) or heterogeneous(2 cases).At the location which masses connected with the empyema,the calcifications were removal,decreased or discontinuous.Conclusion The imaging features of chronic tuberculous pyothorax associated with malignant tumors are of some characteristics,especially the appearances of calcification,soft mass and haziness of fat plane are more valuable for diagnosis.
