摘　　要：目的探讨静脉注射毒品致脓毒性肺栓塞(SPE)的MSCT表现,提高对该病的认识。方法回顾性分析16例静脉吸毒者致SPE的MSCT表现。结果多种形态病灶并存,病灶主要分布于肺外周带或胸膜下。①肺内斑片状、片状模糊阴影9例(56.25%),其中双侧浸润性阴影8例,单侧浸润性阴影1例;②结节影12例(75.00%);③空洞影8例,占50.00%;④肺气囊14例,占87.50%;⑤6例CTPA表现肺动脉充盈缺损2例,表现正常4例。另伴有胸腔积液10例及液气胸3例。结论MSCT检查是诊断静脉应用毒品致SPE重要的方法,肺动脉充盈缺损是本病的直接征象,多发周边或胸膜下的气囊、结节伴或不伴空洞是本病较为特征性的表现。Objective To analyze MSCT characteristics of septic pulmonary embolism （SPE） caused by intravenous drug and to improve diagnosis. Methods The MSCT findings of 16 patients of SPE induced by intravenous drug were analyzed retrospectively from March, 2001 to September, 2008. Results Peripheral or sub-pleural zones were commonly affected mainly within upper lung. Patchy, nodular and cavity shadows were detected respectively in 9 （56.25%）, 12 （75.00%） and 8 patients （50.00 % ）, while pulmonary cysts in 14 patients （87.50%）. Six patients underwent CTPA, and pulmonary arteries filling defect was found in 2 patients. Pleural effusion and pneumothorax were also found in 10 and 3 patients, respectively, whereas miscellaneously shaped lesions were deteced in all 16 patients. Conclusion MSCT is an important method for diagnosing SPE caused by intravenous drug abuse. Pulmonary arteries filling defect is the direct sign and the cysts and nodular shadow with or without cavity in peripheral or sub-pleural pulmonary zones are characteristic findings.
