目的探讨脓毒性肺栓塞(SPE)的高分辨CT(HRCT)表现。资料与方法回顾分析11例SPE患者的胸部HRCT表现。结果11例SPE的HRCT表现为实变及磨玻璃影、结节、楔形阴影、空洞、胸膜改变(如胸腔积液)等征象。其中52%结节影及37%楔形阴影可见“滋养”血管。7例经治疗后肺部改变消失。结论周围性分布的结节影、楔形阴影,结节影、楔形阴影内空洞形成以及与结节影及楔形阴影相连的血管影是SPE较为特征性的HRCT表现,对早期诊断及指导临床治疗有重要意义。
Objective To investigate the high resolution CT (HRCT) manifestations of septic pulmonary embolism (SPE). Materials and Methods Retrospective analysis of thoracic HRCT manifestations in 11 cases of SPE. Results The HRCT manifestations of SPE in 11 cases were those of solidified and ground glass, nodules, wedges, voids and pleural changes such as pleural effusion. Of these, 52% of nodules and 37% of wedges were visible “nourish” blood vessels. Seven cases of lung changes disappeared after treatment. Conclusion The peripheral distribution of nodules, wedges, nodules, voids in wedge-shaped shadows, and vasculogenic images associated with nodules and wedges are SPE-specific features of HRCT. Early diagnosis and guidance for clinical treatment are Significance.
