肺部炎性假瘤的CT表现及价值探讨

目的回顾分析肺部炎性假瘤的CT表现,探讨CT对本病的诊断价值。方法对病理证实的23例肺部炎性假瘤病例的CT表现进行回顾分析,总结并讨论其诊断价值。结果23例病例发病部位不定,形态大小不一,病灶密度多数较均匀(16例),边缘较光滑锐利12例,边缘模糊11例,其中部分病例可见"浅分叶征"、"桃尖征"及短粗毛刺等征象。增强扫描可见病灶明显强化,高分辨率计算机体层X线摄影扫描显示病灶周围可见肺纹理增多增粗,迂曲粗大的血管纹理聚集征象,且有病例有包膜形成等。结论肺部炎性假瘤CT表现缺乏特异性,但仍有很多征象对本病有重要的提示及诊断作用。

CT Appearance of Pulmonary Inflammatory Pseudotumor and Its Value

Objective To retrospectively analyze the CT performance of pulmonary inflammatory pseudotumor, as well as to investigate the diagnostic value of CT scan. Methods Retrospective analysis was made on the CT appearance of 23 cases with definite pulmonary inflammatory pseudotumor, by pathological diagnosis. Information related to its diagnostic value was debated. Results Information about the 23 eases showed that this pseudotumor can be found anywhere in the lung with different size and shape. Most focus has uniform density （16cases）. Focuses in 12 cases showed smooth and sharply edge. Focuses in 11 cases showed ambiguity edge. And part of these cases showed ＂superficial sublobe sign＂, ＂peach point signe＂ and short wide burrs. Enhancement scaning demonstrated obvious strengthening, high resolution computerized tomography displayed that pulmonary markings became malt and thickening, surrounding the focus,winding gross vascular lake became circuity and gross and gathered together,and some revealed amicula. Conclusion The CT appearance of pulmonary inflamematory pseudotumor lacks specificity, but many signs are still important for diagnosis of this disease.
