目的探讨MSCT在急性阑尾炎中诊断价值。方法回顾分析2010年1月—2010年12月郑州市中心医院30例患者,观察其在MSCT(Philips公司Brilliance 64层螺旋CT)中的表现,均行MPR、CPR,行增强扫描10例。结果 25例患者阑尾局部或全部管腔直径增粗,增粗阑尾管腔呈实性状,或伴有阑尾壁增厚;阑尾结石8例,7例钙化结石位于管腔内,1例位于腔外,结石轮廓模糊,形态不规则;回盲部肥厚10例,表现为末端回肠及盲肠顶部管壁广泛肥厚或局限性增厚;阑尾周围炎21例,表现为回盲部周围脂肪组织密度增高,呈斑点状或条纹状密度增高改变;阑尾脓肿3例,脓肿包块较局限,呈团块状影。误诊2例,经手术证实阑尾腺癌及盲肠憩室炎各1例。结论 MSCT能更加准确的诊断急性阑尾炎,也可为急性阑尾炎术前计划提供帮助。
Objective To investigate the diagnostic value of MSCT in acute appendicitis. Methods Thirty patients in Zhengzhou Central Hospital from January 2010 to December 2010 were retrospectively analyzed. Their performance in MSCT (Philips Brilliance 64-slice spiral CT) was observed. All patients underwent MPR, CPR and enhanced line scan. Results The diameter of the lumen of the appendix was increased in 25 cases. The lumen of the appendix was augmented or the appendix wall was thickened. The appendix stones were located in the lumen in 8 cases, calcified calculi in 7 cases and lumen in 1 case , The stone outline fuzzy, irregular shape; ileocecal hypertrophy in 10 cases, the performance of the distal ileum and cecum top of the wall extensive hypertrophy or limited thickening; appendicitis in 21 cases, showed increased density of adipose tissue around the ileocecal, A spot or striped density increased change; appendix abscess in 3 cases, abscess mass is more limited, showed a mass-like shadow. Two cases were misdiagnosed, one case of appendectomy and cecal diverticulitis were confirmed by operation. Conclusions MSCT can diagnose acute appendicitis more accurately and can also help preoperative planning of acute appendicitis.
