目的：探讨肺错构瘤的影像诊断问题。方法：回顾性分析经手术病理证实的２６例肺错构瘤，所有病人均有Ｘ线平片，１１例体层及６例ＣＴ检查。并同４５例结核球和９８例周围性肺癌进行对照研究。结果：肺错构瘤的主要Ｘ线征象：中央型３例为叶支气管内或肺门区肿物，周围型２３例均为圆形或椭圆形肿块，病灶平均直径２．２ｃｍ，多数边缘光整，３５％病灶有钙化，以斑点状或环状多见。本病与结核球、肺癌在病灶的大小、边缘及密度等均有不同之处。本病ＣＴ表现病灶内常可显示钙化和脂肪。结论：传统Ｘ线对周围性错构瘤的诊断及其与结核球、周围性肺癌的鉴别很有帮助。ＣＴ检查可补充平片、体层之不足，可显示病灶内钙化或／和脂肪特征。
Objective: To investigate the imaging diagnosis of pulmonary hamartoma. Methods: Twenty-six cases of pulmonary hamartoma confirmed by surgery and pathology were retrospectively analyzed. All patients had X-ray plain films, 11 cases of body layer and 6 cases of CT examination. And compared with 45 cases of tuberculosis and 98 cases of peripheral lung cancer. Results: The main X-ray signs of pulmonary hamartoma: 3 cases of central type were intra-bronchial or hilar masses, and 23 cases of peripheral type were all round or oval masses. The average diameter of the lesions was 2.2 cm. In the whole, 35% of the lesions were calcified, more common in spots or rings. The disease and tuberculoma, lung cancer in the lesion size, edge and density are different. The CT appearance of this disease often shows calcification and fat within the lesion. Conclusion: The traditional X-ray diagnosis of peripheral hamartoma and its identification with tuberculosis, peripheral lung cancer is helpful. The CT examination can supplement the deficiency of the plain film and the body layer and can show the calcification or/and fat characteristics within the lesion.
