阑尾黏液性囊腺瘤的多层螺旋 CT影像表现

目的：分析阑尾黏液性囊腺瘤的多层螺旋CT 影像表现，了解其影像特征，提高对其诊断的准确率。方法回顾性分析我院18例经手术病理证实的阑尾黏液性囊腺瘤的CT及临床资料。结果 CT 表现为右下腹部圆形或类圆形囊性病灶，囊腔扩张明显，M PR重组图像比较有特征性，主要表现为中间膨胀，两端较细的梭形病灶，也有少部分表现为管状或腊肠状，内容物呈水样低密度，部分囊壁可见钙化。结论 CT 扫描及M PR重建可清晰显示病灶的形态及毗邻关系，具有一定的特征性，对该病的诊断和鉴别诊断具有重要的帮助，有利于术前的正确诊断。

The multi-slice CT imaging findings of appendiceal mucinous cystadenoma

Objective To analyze the imaging features of appendiceal mucinous cystadenoma and improve the diagnosis of the disease .Methods The CT and clinical data of 18 patients with appendiceal mucinous cystadenoma confirmed by surgery and pathology were analyzed retrospectively .Results Round or oval cystic lesions were manifested in the right lower quadrant ,and the capsular spaces were dilated obviously .MPR images were charac-teristic ,in which the lesions mostly manifested as fusiform dilated in the middle and fine in both sides .Also a few of lesions manifested as tubiform or botuliform .The contents of the lesions were low density like water ,and calcifica-tion walls were found in some cases .Conclusion CT scans and MPR characters in the shape and adjoin are helpful for diagnosis and differential diagnosis of appendiceal mucinous cystadenoma before surgery .
