单发肺炎性假瘤24例临床X线分析

CLINICAL ROENTGENOLOGIC ANALYSIS OF 24 CASES WITH SINGLE INFLAMMATORY PSEUDOTUMORS OF LUNG

目的 :分析单发性假瘤的临床 X线表现 ,提高诊断及鉴别诊断水平。方法 :对手术切除、CT导引下肺穿刺活检证实的 2 4例肺炎性假瘤的临床、X线胸片及 CT片进行回顾性分析。结果 :在 2 4例肺炎性假瘤中 ,79% ( 1 9/ 2 4 )的肿块位于肺的外周 ,贴近胸膜面可伴有胸膜肥厚 ;75% ( 1 8/ 2 4 )的肿块边缘光滑规整 ,其内密度均匀 ;6 7% ( 8/ 1 2 ) CT增强值大于 6 0 Hu;CT导引下肺穿刺活检定性诊断率为 90 % ( 1 0 / 1 1 )。结论 :X线胸片和 CT是诊断肺炎性假瘤的主要方法 ,CT导引下肺穿刺活检定性诊断率高 ,可作为组织学诊断的首选方法。

Objective:To increase the reliability of diagnosis and differential diagnosis of single inflammatory pseudotumors of lung(IPL) by analyzing the clinical roentgenologic appearance.Methods:The clinical roentgenologic appearance of 24 cases with single IPL from January 1990 to October 2001 was retrospectively studied.All cases were proved by clinical surgery and pathological findings.Results:In 24 cases,79 percent of the masses were at the margin of the lung,the ones near the pleural with concomitant pleural thickness;75 percent of the masses showed well defined margin and homogeneous attenuation;67 percent of the masses had an enhanced CT value more than 60 Hu.The diagnostic accuracy was 90 percent by CT guided biopsy.Conclusion:Chest radiography and CT were main diagnostic methods of IPL.
