目的：肺错构瘤是肺内最常见的良性肿瘤。但因临床表现无特异性而容易误诊。为提高对本病的诊治水平，我们从临床表现、胸部Ｘ线、手术及病理等方面探讨肺错构瘤的诊断与鉴别诊断。方法与结果：采用回顾性资料分析发现，本组肺错构瘤肺内型１５例，腔内型１２例；平均年龄４９９岁，男女比例为１６７∶１。临床症状少而轻。Ｘ线表现为圆形、类圆形阴影，肿块直径≤４ｃｍ者占８７５％，位于肺周边部位者占７５％。结论：肺错构瘤可经影像学检查提示诊断，确诊有赖于手术切除病理证实。
Purpose: Pulmonary hamartoma is the most common benign tumor in the lung. However, due to non-specific clinical manifestations and easy misdiagnosis. In order to improve the diagnosis and treatment of this disease, we discuss the diagnosis and differential diagnosis of pulmonary hamartoma from clinical manifestations, chest X-ray, surgery and pathology. Methods and Results: The retrospective data analysis found that this group of pulmonary hamartoma pulmonary endometriosis in 15 cases, 12 cases of endovascular; average age 49 9 years old, male to female ratio of 1 67: 1. Clinical symptoms are small and light. X-ray showed a round, round-shaped shadow, mass diameter ≤ 4cm accounted for 87 5%, located in the peripheral parts of the lung accounted for 75%. Conclusions: Pulmonary hamartoma can be diagnosed by imaging examination, confirmed by surgical resection pathology confirmed.
