目的总结尘肺合并肺癌的影像学特点,提高对该病的认识,减少误诊及漏诊。方法回顾性分析本院3年内诊断的尘肺合并肺癌患者X线片和CT表现,总结尘肺合并肺癌的影像学特点。结果 8例尘肺合并肺癌患者有第一次就诊时疑诊肺癌的1例,3例出现X线片上肿块被肺纤维化掩盖、牵拉,使肿块失去正常形态、密度,降低了肺癌的检出诊断率;CT诊断使尘肺合并肺癌患者的肿块更具体,并可发现隐匿部位肿块,更精确地发现周围病变的改变,并可发现纵隔及腋窝淋巴结转移。结论 CT诊断能提高尘肺合肺癌患者的病变检出率,有利于尘肺合并肺癌的诊断。
Objective To summarize the imaging features of pneumoconiosis combined with lung cancer and to improve the understanding of the disease and reduce the misdiagnosis and missed diagnosis. Methods Retrospective analysis of the X-ray and CT findings of pneumoconiosis patients with pneumoconiosis diagnosed within 3 years in our hospital. The imaging features of pneumoconiosis with lung cancer were summarized. Results Of the 8 patients with pneumoconiosis who had pneumoconiosis at the first visit, 1 patient had suspected lung cancer and 3 patients had X-ray lumps covered by pulmonary fibrosis and pulled to lose the normal morphology and density of the lumps and reduced the detection of lung cancer Diagnosis rate; CT diagnosis of pneumoconiosis patients with lung cancer more specific, and can be found in hidden parts of the tumor, more accurately detect changes in the surrounding lesions, and found mediastinal and axillary lymph node metastasis. Conclusion CT diagnosis can improve the detection rate of pneumoconiosis patients with pneumoconiosis, which is beneficial to the diagnosis of pneumoconiosis with lung cancer.
