【摘要】 目的 探讨回盲部周围感染性病变的临床及MSCT表现。方法 回顾性分析147例经术后病理证实或临床确诊的回盲部周围感染性病变的CT资料及临床表现。结果 147例患者中,阑尾炎119例,其中2例为回盲部肿瘤合并急性阑尾炎;结肠憩室炎11例,5例并发憩室内粪石(其中3例出现穿孔);腹腔脓肿14例,9例病灶呈周边稍高密度、中央低密度包块,5例表现为蜂窝状不均匀低密度影,增强扫描脓肿壁及分隔明显强化;右侧输卵管脓肿3例,表现为右侧附件区腊肠样低密度影。结论 CT检查对显示回盲部周围感染性病变的敏感性及特异性较高,回盲部周围各种感染性病变MSCT表现有较多重叠,疾病临床表现类似、缺乏特异性,易造成漏诊及误诊。更多还原

【Abstract】 Objective To summarize the clinical and MSCT manifestations of infectious lesions around the ileocecus.Methods The clinical and CT manifestations of 147 patients with infectious lesions around the ileocecus were analyzed retrospectively.All of patients were confirmed by postoperative pathology or clinical diagnosis.Results Of 147 patients,there were 119 cases of appendicitis,including 2 cases of ileocecal tumor combined with acute appendicitis;11 cases of colonic diverticulitis,including 5 cases with bezoars in diverticulum(perforation occurred in 3 cases);14 cases of abdominal abscess(9 cases showed peripheral slightly hyper-density and central hypo-density masses,and 5 cases showed the faveolate inhomogeneous hypo-density,significantly enhanced walls and septum on enhanced CT imaging);3 cases of right tubal abscess showing sausage-like hypo-density.Conclusion CT shows high sensitivity and specificity for the diagnosis of infectious lesions around the ileocecus.MSCT manifestations are more overlapped among different infectious lesions around the ileocecal region,and clinical features of these diseases are similar,which can cause missed diagnosis and misdiagnosis.更多还原
