肺部非典型矽肺融合块的临床X线表现有时同外围型肺癌很相象,鉴别诊断常感困难,文献报导将矽肺误诊而手术者并不少见,我们也有过沉痛教训,说明两者在鉴别诊断上存在着需要解决的问题。我院自1968年4月至1979年8月的11年间,在疑难的胸部疾病诊断中,采用额面倾斜位体层摄影检查共154例,经过整理临床与X线资料完整者28例,其中肺癌19例(6例为粉尘作业工人),经病理和痰细胞学检查证实,矽肺融合块9例,具有可靠的职业史,随访5年以上,有逐年复查的一套胸片,认为诊断无疑者。年龄在40～60岁之间,平均年龄47岁,将着重其X线征象分析,并结合文献讨论总结其经验教训以提高认识。
Clinical X-ray findings of atypical pulmonary silicosis in lungs are sometimes very similar to peripheral lung cancers. Differential diagnosis is often difficult. It has been reported in the literature that misdiagnosis of the silicosis is not uncommon for surgery, and we have had painful lessons indicating that both There are problems in diagnosis that need to be solved. Our hospital from April 1968 to August 1979 11 years, in the diagnosis of difficult chest disease, using frontal tilt stereotaxis examination of a total of 154 cases, after finishing the clinical and X-ray data of the complete 28 cases, of which Lung cancer in 19 cases (6 cases of dust workers), confirmed by pathology and sputum cytology, silicosis block in 9 cases, with a reliable occupational history, followed up for 5 years, a review of a set of chest radiographs every year, no doubt that the diagnosis By. The age of 40 to 60 years old, with an average age of 47 years, will focus on its X-ray signs of analysis, combined with the literature to discuss its lessons to improve awareness.
