1、多层螺旋CT在阑尾粘液性囊肿诊断中的应用价值熊建国杜勇信阳市中心医院影像科河南省信阳市464000摘要：目的探讨多层螺旋CT对阑尾粘液性囊肿的诊断方法及临床价值。方法回顾性分析2007年5月至2014年6月我院经多层螺旋CT诊断的9例阑尾粘液囊肿患者临床及影像学资料，9例患者均经术后病理检查确诊。结果CT平扫示病灶为右下腹阑尾区囊性包块，囊壁薄、边缘光滑，呈类圆形或椭圆形,密度均匀，最大径2.5〜4.5cm，8例CT值7〜19HU,1例呈软组织密度，周围肠系膜脂肪清晰，密度无明显增高；5例伴阑尾周
2、围炎症者盲肠腔变形，囊壁无明显增厚，可见盲肠及回肠末端轻度弧形受压。增强扫描中5例无明显增强，4例囊壁轻度环形增强，囊壁均匀、光滑，可见点状钙化，囊内容物未见增强，CT值14〜17HU。9例患者均经手术治疗，术后病理检查结果与CT诊断结果相符。结论多层螺旋CT检查及MPR重建技术可连续及完整地观察阑尾及周围组织情况,对阑尾粘液囊肿有较高的术前确诊率，有利于手术方案制定及并发症的预防。关健词：阑尾粘液囊肿；多层螺旋CT;诊断Abstract：ObjectiveToexploretheapplicat
