创伤性湿肺的螺旋CT诊断(附60例分析)

目的探讨螺旋CT对创伤性湿肺诊断及鉴别诊断的价值。方法回顾性分析了60例创伤性湿肺病人的螺旋CT资料,观察其CT征象,并加以总结。结果CT表现分为4型:(1)间质型10例,肺血管影增粗、模糊,(2)弥漫实变型15例:肺实质内散在斑点状、小片状稍高密度灶;(3)云雾型20例,呈磨砂玻璃改变的云雾状稍高密度灶(即“面纱征”);(4)节段实变型15例,大片状或呈叶、段分布的高密度灶。结论螺旋CT能够明确显示创伤性湿肺的部位、类型、范围和发现合并伤的存在,是目前诊断创伤性湿肺有效的检查手段之一。

Spiral CT Diagnosis of Traumatic Wet Lung ( An Analysis of 60 Cases )

Objective To explore the diagnostic and differential diagnostic value of spiral CT in traumatic wet lung.Methods CT features of traumatic wet lung in 60 cases were retrospectively analyzed and summarized. Results CT features of wet lung included 4 types:(1)the interstitial type in 10 cases,appeared as thicknees and blurring of the shadow of pulmonary blood vessels;(2)the disseminated consolidation type in 15 cases appeared as scattered mottling or small patch foci with slight high density in pulmonary parenchyma;(3)the mist type in 20 cases appeared as slight high density with ground-glass like cloudy shadow;(4)the type of segmental consolidation in 15 cases appeared as high dense foci with large patch in segmental distribution.Conclusion Spiral CT can well detect the site, type, extent of traumatic wet lung and other injury. It is the most optimal means at present for traumatic wet lung.
