| 摘 要： | 目的报告胆囊腺肌增生症的MSCT表现特点,探讨CT诊断价值。资料与方法回顾性分析经手术、病理证实的15例胆囊腺肌增生症的CT表现。15例中,弥漫型1例,节段型7例,局限型6例,混合型(局限型和节段型合并存在)1例。所有患者均先行B超检查,11例行CT平扫及多期增强扫描,4例仅行CT平扫,部分病例采用CT薄层重组及多平面重组(MPR)技术观察。结果 CT术前正确诊断13例,其中显示罗-阿氏窦(Rok itansky-Ashoff sinus,RAS)9例;B超术前仅正确诊断2例(弥漫型及局限型各1例)。CT表现为胆囊壁弥漫性或局限性增厚,部分腔内、外面毛糙不整。增强扫描后动脉期病变区黏膜及部分黏膜下组织明显强化,门静脉期及延迟期强化逐渐向肌层及浆膜面扩展,呈明显均匀或不均匀强化;增厚胆囊壁内大小不等无强化的RAS及壁内微小结石,为胆囊腺肌增生症的特征性CT征象。结论 CT对胆囊腺肌增生症具有较高诊断价值,RAS的显示及壁内结石则具有定性诊断价值;胆囊腺肌增生症分型可为临床手术治疗提供重要信息。

| Abstract: | Objective To discuss the features of gallbladder adenomyomatosis(GBA)in order to evaluate the value.Materials and Methods Fifteen cases with GBA(1 diffuse,7 segmental,6 localized and 1 mixed)comfirmed by histopathology were retrospectively reviewed.All these cases were performed by ultrasonography at first.11 cases were performed by CT plain and many phase enhancement scanning,while 4 cases just by plain scanning.Results 13 of 15 cases were correctly diagnosed by CT,in which 9 cases displayed the Rokitansky... |
