摘　　要：目的:探讨CT诊断阑尾黏液囊肿的影像学依据及临床价值。方法:回顾性分析我院15例经手术病理证实的阑尾黏液囊肿的CT表现及临床资料。结果:阑尾黏液囊肿的CT表现为右下腹紧邻回盲部大小不等的囊性病灶,呈圆形、类圆形或长管状,密度比较均匀,部分病灶内见钙化或线状分隔。囊肿壁薄、光滑,可有钙化,增强扫描示囊肿壁强化,囊内容物未见明显强化。病灶周围脂肪间隙清晰,邻近肠管可有受压、变形改变。结论:阑尾黏液囊肿临床罕见,且临床表现无特异性,术前诊断较困难,术中如果囊肿破裂会形成腹膜假性黏液瘤等一系列并发症,预后较差。而其CT表现具有一定的特征性,结合MPR重建技术可连续、完整地观察阑尾及周围组织情况,提高阑尾黏液囊肿的术前诊断率,有利于手术方案的制定及并发症的预防。Objective:To explore the imaging basis and clinical value of CT in the diagnosis of appendiceal mucocele(AMC).Methods:CT findings and clinical data of 15 cases of AMC confirmed by operation and pathology were retrospectively analyzed.Results:AMC on CT showed cystic lesions of different sizes in the right lower abdomen adjacent to ileocecal region,round,round or long tubular,with relatively uniform density.Calcification or linear septation were seen in some lesions.The cyst wall was thin and smooth with calcification.On enhanced scan,the cyst wall was strengthened,and the contents of the cyst were not obviously strengthened.The fat space around the lesion was clear,and the adjacent intestinal canal could be compressed and deformed.Conclusion:AMC is rare in clinic,and its clinical manifestation is not specific.Preoperative diagnosis is difficult.If the cyst ruptures during operation,a series of complications such as pseudomyxoma peritoneum will occur.The prognosis is poor.CT manifestations have certain characteristics.Combined with MPR reconstruction technology,appendix and surrounding tissues can be continuously and completely observed,and the preoperative diagnosis rate of appendix mucocele can be improved,which is conducive to improving the preoperative diagnosis rate of appendix mucocele.The formulation of surgical procedures and prevention of complications.
