肺内良性肿块误诊分析

Analysis of the misdiagnosis of several benign pulmonary masses

目的 提出几种肺内良性肿块的鉴别诊断方法。 方法 分析 10 8例肺内良性肿块的误诊情况。 结果 病例中肺结核球、炎性假瘤、硬化性血管瘤、曲菌病、错构瘤及肺隔离症占大多数 ,术前误诊为其他病变 4 3例 ,误诊率 39.8%。 结论 术前肺内良性肿块的鉴别诊断相当困难 ,对不能确诊的肺内孤立性病灶应持积极手术的态度 ,且手术中一定要做快速冰冻活检 ,以便根据性质来判定肺切除的范围。

Objective For the purpose to find the methods of differential diagnosis in several benign pulmonary masses. Methods 108 cases of benign pulmonary masses which were confirmed by pathology of surgical specimens postoperatively were retrospectively analyzed. Results The tumors mainly include pulmonary tuberculoma,Inflammatory pseudotumor,Sclerosing hemangioma,aspergillosis,hamartoma,pulmonary sequestration.Of all the patients 43 cases were misdiagnosed preoperatively and the rate of misdiagnosis was 39.8%. Conclusion It is difficult to differentiate benign pulmonary masses from each other preoperatively.In our experience when the preoperatively diagnosis of pulmonary isolated lesions has been uncertain,active surgery should be carried out.And the pathological studies of the frozen section during operation is necessary,for which could help us to get the verdict of tumors' character and decide the optimal margin of surgery.
