MSCT对卵巢子宫内膜异位囊肿的诊断分析
Modern Medical Imagelogy(2019)
Abstract
目的:探讨卵巢子宫内膜异位囊肿的MSCT表现,提高对该病的诊断水平.方法:回顾性分析经手术和病理证实的36例卵巢子宫内膜异位囊肿的MSCT表现.结果:16例为一侧卵巢发生(左侧10例,右侧6例),双侧20例,9例单囊,27例多囊.5个囊肿呈分叶形或不规则形,其余囊肿形态呈类圆形或椭圆形,多囊者大小不一囊肿簇拥聚集,其中12例表现为一个大囊外多个子囊,7例子囊呈串珠状排列.多数囊肿密度较高,少数为水样密度或新鲜出血密度,多囊者各囊之间密度高低不一,17个囊肿内见液液平面,上低下高,增强扫描各期囊内均无强化.囊壁厚度平均3.5mm,多囊者各囊间囊壁厚薄不一,增强扫描各期呈持续性强化,多囊者各囊囊壁强化不一.全部病灶均与子宫紧贴,12例与肠管粘连,14例与膀胱壁脂肪间隙消失,10例与盆壁粘连.结论:卵巢子宫内膜异位囊肿的MSCT征象及其MPR具有一定的特征性,对大多数病变可作出明确诊断.
