【摘要】 目的 :探讨肺错构瘤的临床、X线及CT影像特点。方法 :6 7例肺错构瘤 ,平均年龄 5 0 4岁 ,无症状体检发现 40例 (5 9 7% )。全部病例均有胸部正侧位照片 ,其中 42例有肺门及病灶断层照片。CT检查 10例 ,支纤维镜检查 18例 ,全部病例均有病理证实。结果 :本组病例X线分型大多数为肺实质型 ,X线表现除具有良性肿瘤的一般征象外 ,约 12 %的瘤体内可见斑点状或斑片状钙化 ,爆米花样钙化对肺错构瘤的定性诊断有重要意义。病理以软骨型多见。结论 :X线及CT薄层扫描对本病的发现与诊断有重要作用更多还原

【Abstract】 Purpose:To recognize the X ray and CT characteristics of pulmonary hamartoma. Methods:67 cases of pulmonary hamartoma were analyzed. The average age was 50.4. 40 cases (59.7%) were asymptomatic and found by physical examination. All cases were proved with PA and lateral chest radiographs. 42 of these cases were given tomography of hilas and lesion. 10 cases were given CT examination, 18 cases had bronchoscopy examination.Results:All cases were proved by pathology and the chondromoid type was the most common. Most of the cases were parenchymal type in X ray examination; X ray signs:12% of the tumors show spotty and patchy calcification besides other findings of benign tumor in X ray examination. The popcorn calcification had important significance in diagnosis of plumonary hamartoma.Conclusions:X ray and thin sliced computed tomography play important roles in detecting and diagnosing pulmonany hamartoma.更多还原
