肺内良性肿块的CT与手术对照分析

Study of CT imaging of pulmonary benign masses

目的 :探讨肺内良性肿块的CT表现及其诊断价值。方法 :对照分析经手术及病理证实的 10 2例肺内良性病变的CT表现 ,其中肺炎性假瘤 45例 ,结核瘤 42例 ,肺血管瘤 5例 ,错构瘤 3例 ,肺隔离症 3例 ,曲霉菌病 2例 ,肺纤维瘤和肺血肿各 1例。结果 :肺炎性假瘤、肺结核瘤、肺血管瘤、肺隔离症及曲霉菌病的CT符合率分别为 3 3 .3 %、73 .8%、2 0 %、10 0 %和 10 0 %。结论 :通过仔细对照分析和重新评判 。

Objective:To study the CT findings of the pulmonary benign masses and to assess their diagnostic value.Methods:CT findings in 102 patients with pulmonary benign masses confirmed by surgery and pathology were analyzed.They included inflammatory pseudotumors (45 cases),tuberculomas (42 cases),angioma (5 cases),hamartoma (3 cases),lung sequestration (3 cases),aspergillosis (2 cases),pulmonary fibroma (1 case),and pulmonary hematoma (1 case). Results: CT diagnosis coincided with final diagnosis in 33.3% patients with inflammatory pseudotumors,73.8% patients with tuberculomas,20% patients with pulmonary angioma,and in all patients with lung sequestration and pulmonary aspergillosis.Conclusion:Most pulmonary benign masses can be diagnosed correctly through careful study and reappraisal of CT findings.
