【摘要】 目的探讨肺癌性淋巴管炎的X线、CT表现及其临床应用价值。方法回顾性分析40例经支气管镜活检、胸膜活检或开胸肺活检证实的肺癌性淋巴管炎的X线、CT及HRCT征象,评价其影像学诊断的临床应用价值。结果肺癌性淋巴管炎主要表现为支气管血管束串珠状增粗、小叶内细网结节状影、小叶间隔小串珠状增厚、小叶核心结节、胸膜结节、肺门和/或纵隔淋巴结增大、胸腔积液及双肺弥漫分布的小空泡样阴影。结论肺癌性淋巴管炎的影像学表现具有一定特征,其影像诊断以HRCT为最佳,但优质的胸部X线平片和CT平扫可以提供一些有益征象。更多还原

【Abstract】 Objective To study the x-ray and CT findings of pulmonary lymphangitic carcinomatosis(PLC),and to discuss it’s clinical value.Methods The imaging materials of 40 cases’ PLC which were proved by bronchoscopic or pleural or open-lung biopsy were retrospectively analyzed,and the clinical application of imaging diagnosis were investigated.Results The major features of PLC included: beaded thickened bronchovascular bundles,intralobular small reticular and nodular shadows,small beaded thickened interlobular septums,lobular core nodes,pleural nodes,tumescent pulmonary hilar and/or mediastinal lymph nodes,hydrothoraxes,small vacuolar opacities diffusely distributed over the bilateral lung.Conclusions PLC possess relative imaging feature,particularly HRCT is the most satisfactory method in diagnosing PLC,but the super-quality thoracic plane film and CT traditional scan can supply some useful signs of PLC.更多还原
