阑尾黏液性囊腺瘤的CT诊断价值

目的：探讨阑尾黏液性囊腺瘤CT表现,提高其术前正确诊断水平。方法：经手术病理证实的7例阑尾黏液性囊腺瘤均行16层螺旋CT检查,常规行CT平扫加动态增强扫描。回顾性分析其CT表现。结果：所有患者术前CT均未能做出正确诊断,7例均表现为右侧髂窝处边缘光整的椭圆形、类圆形囊性肿块,MPR图像上表现为长椭圆形或类圆形,囊壁均匀薄壁4例,囊壁厚度不均并见乳头状突起及囊内分隔3例;动态增强扫描呈中等程度强化3例,无明显强化4例。阑尾管壁增厚、肿块邻近脂肪模糊1例,伴有腹腔内多发囊性肿块及腹腔积液1例。结论：当CT检查发现右侧髂窝处囊性肿块,囊壁厚度不均伴或不伴有囊内分隔及乳头状突起等CT表现时,影像科医师应考虑到阑尾黏液性囊腺瘤的诊断,从而避免发生医源性腹腔假性黏液瘤。

Diagnostic value of CT for appendiceal mucinous cystadenoma

Objective:To discuss the CT performance of appendiceal mucinous cystadenoma for improving the preoperative diagnosis.Methods:Seven cases of appendiceal mucinous cystadenoma confirmed by pathology were collected and evaluated.The relevant references were also reviewed.Results:No correct diagnosis was made preoperatively for all the seven cases.The relatively characteristic features of CT included:oval or round cystic mass with neat edge in the right iliac fossa,and long oval mass on MPR in all 7 cases.Unifor...
