阑尾粘液囊肿的CT诊断及其临床价值

Diagnostic value of CT Findings in Mucocele of the Appendix

目的:评估阑尾粘液囊肿CT检查的术前诊断价值。方法:对7例经手术病理证实的阑尾粘液囊肿的 CT表现及临床资料进行回顾分析。结果:阑尾粘液囊肿在CT上表现为右下腹部紧邻回盲部的大小不等囊性病灶,圆形、类圆形或长条状,部分病灶内可见线状分隔影。囊肿壁光整、可有强化,病灶内容物无明显强化。病灶周围结构清晰,邻近肠管均有不同程度管腔受压变窄改变。2例囊肿近端见结石影,1例示囊肿近段阑尾壁增厚、管腔变窄。未经治疗的 1 例囊肿1周后体积明显缩小。结论:阑尾粘液囊肿罕见且临床表现无特异性,但CT表现具有特征性,可在术前作出明确诊断。

Objective:To assess the value of computed tomography (CT) in the preoperative diagnosis of appendical mucous cyst.Methods:Retrospectively study the CT findings and their clinical presentation of seven cases with appendiceal mucous cyst.Results:The size of lesions was various in the lower right abdomen closely adjacent to the cecum,the cysts were round or oval or long marsupial in shape on CT scan.the walls of cyst were smooth and enhanced or not enhanced. Thin septa could be seen inside some cysts.All pericystic structures were clear.Stones were found near the cecum in 2 cases.The appendiceal wall was thickened and the cavity was narrowed in one case.The size of lesion in 1 case became smaller after one week without any therapy.Conclusion:Appendical mucous cyst is rare and their clinical presentation is not specific.CT finding were chanacteristic and helpful for correct diagnosis of mucocele of the appendix.
