摘要

目的：探讨海洛因体内藏毒的CT检出以及评价CT在筛查这类案例中的作用。方法：搜集2005年9月5日～2008年4月23日所有疑犯的影像学资料（所有病例均行CT检查，其中42例加做了腹部平片X线检查），回顾性分析最终确诊为海洛因体内藏毒罪犯的腹盆部CT影像学表现（形态、大小、数目、位置和密度）以及腹部X线平片的表现。结果：158例疑犯中124例最终确诊为海洛因体内藏毒者，这与CT检查结果一致。42例腹部平片检查中有2例假阴性结果。CT和腹部平片表现为腹盆部消化道和/或阴道内紧密排列的圆形或卵圆形肠道外异物影，此外还发现了“气环征”和“洋葱皮征”为海洛因体内藏毒的CT特征性表现，对检出这类罪犯有一定作用。结论：海洛因体内藏毒的CT表现具有一定特异性，常规腹盆部CT是检出体内藏毒疑犯的较为精确的一种影像学检查方法。

Abstract

Objective: To determine the value of CT screening in detecting heroin packets hidden in body and to reveal the CT features. Methods: We collected 158 cases of suspected drug packers’ imaging materials(all underwent CT, 42 cases were imaged using plain X-ray film) from September 5th, 2005 to April 23rd, 2008. Abdominal-pelvic CT appearances(shape, size, number, location and density) and abdominal plain X-ray film manifestations were retrospectively observed for those who were finally confirmed as heroin body packers through the passing of evacuated drug packets. Results: Among 158 cases of suspected drug packers in our study, 124 cases were finally diagnosed as heroin body packers. This was consistent with the CT results. However, there were 2 false-negative cases of abdominal imaging taken with plain X-ray film. All of the evacuated heroin body packets were produced mechanically. CT and plain film characteristic findings included the presence of uniform shape, varied density, and well-defined round or ovoid intra-luminal foreign-body shadows arranged closely along the gastrointestinal tract and/or vagina. We also found that the “air-ring sign” and “onion sign” were valuable characteristics that were seen on the CT scan, which helped to positively confirm the detection of heroin packets. Conclusion: Heroin body packing has clearly defined diagnostic features that can be seen with CT. Furthermore, conventional abdominal-pelvic CT is the imaging modality of choice in the evaluation of suspected body packers.
