摘要
【目的】探讨肺部周围型良性肿瘤的影像学诊断与检查方法。【方法】分析51例肺周围型良性肿瘤平片、CT与MRI表现，评价不同检查方法的定性诊断与分类诊断准确性。【结果】51例中肺错构瘤12例、肺畸胎瘤2例、肺脂肪瘤4例、肺纤维组织细胞瘤3例、良性肺组织细胞瘤2例、良性软骨瘤2例、良性淋巴瘤样增生5例、肺海绵状血管瘤1例、肺硬化性血管瘤11例、支气管囊肿8例和肺血管外皮细胞瘤1例。肿瘤结节直径在3cm以下43例，37例结节密度均匀，11可见肿瘤结节内钙化，48例结节边缘光整。全部病例中43例胸部正侧位胸片诊断为良性肿瘤（或可能性大），且其中仅13例（25．6％）分类诊断（如明确诊断为脂肪瘤或错构瘤等）准确；30例CT检查者25例诊断为良性肿瘤，但其中13例（43．3％）分类诊断准确。同时本文对不同的良性肿瘤影像学特征进行了分析。【结论】肺周围型良性肿瘤具有明显的影像学特征；胸部正侧位片仍是最基本和首选的检查方法，常规CT扫描结合薄层CT或高分辨CT（HRCT）扫描是肺良性肿瘤的无创性检查中的最佳检查方法，MRI检查可作为CT的一种补充。
[Objective]To investigate the imaging diagnosis and evaluation of inspection methods of periph eral pulmonary benign tumor. [Methods] Fifty One cases of peripheral benign tumor in lung were enrolled in the study. The X-ray, CT and MRI characteristics were analyzed and the accuracy of qualitative and classification diagnosis by different examination methods were evaluated. [Results]Of all the 51 cases, there were 12 pulmonary hamartoma, 2 pulmonary teratoma, 4 pulmonary lipoma, 3 pulmonary fibrous histiocytoma, 2 pulmonary benign histicytoma, 2 benign chondroma, 5 benign lymphomatoid hyperplasia, 1 pulmonary cavernous hemangioma, 11 pulmonary sclerosing hemangioma, 8 bronchogenic cyst and 1 pulmonary hemangiopericytoma. The nodule diameter of 43 cases was lower than 3cm. The density of nodule of 37 cases was uniform. Intra-nodular calcification was found in 11 cases. The nodule edge of 48 cases was smooth. Among all cases, 43 cases was diagnosed as benign tumor and the classification diagnosis of 13 cases （25.6 %） was accurate （such as a clear diagnosis of lipoma or hamartoma） by chest posterior-anterior and lateral chest film. Of 30 cases by CT, 25 cases were diagnosed as benign tumor and the classification diagnosis of 13 cases （43.3%） was accu rate. [Conclusion]Peripheral pulmonary benign tumor has obvious imaging characteristics. Chest X-ray film still is the most fundamental and preferred examination method. Conventional CT combined with thin layer CT scan or HRCT scan is the best non-invasive method for the examination of pulmonary peripheral benign tumor, and MRI examination can be used as a complement to CT.
