脓毒性肺栓塞的高分辨CT表现初探

High Resolution CT Findings of Septic Pulmonary Embolism

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 evaluate the high resolution CT（HRCT） findings of septic pulmonary embolism.Materials and Methods The HRCT findings in 11 patients with septic pulmonary embolism were analyzed retrospectively.Resu-lts The HRCT findings presented as consolidation,ground glass opacity,nodule,wedge shaped opacity,cavity and pleural effusion.Transverse images showed that 52% of the nodules and 37% wedge shapedlesions had ＂feeding vessels＂.Most of lesions disappeared after therapy.Conclusion The HRCT findings of septic pulmonary embolism have great value to make early diagnosis and clinical therapy.
