目的探讨局限型胆囊腺肌增生症(GBA)的CT分型及临床意义。方法搜集38例经手术病理证实的局限型GBA患者的临床及影像资料,男23例,女15例,平均年龄57岁。全部病例均行多层螺旋CT(MSCT)平扫及多期增强扫描,原始数据行CT薄层重组及多平面重组(MPR),根据CT表现对局限型GBA进行分型。结果38例局限型GBA中,基底型9例,胆囊底部帽状、半环状或扁平状轻度增厚;壁内型3例,底部局限性增厚向腔内隆起;乳头型24例,增厚底部呈乳头状向腔外凸出;混合型2例,底部增厚同时向腔内、外隆起。各型病例在平扫及多期增强扫描均可见分布于整个增厚壁内多发大小不等的罗-阿氏窦(RAS)。结论局限型GBA的CT分型有望为临床治疗及手术方案的选择提供参考依据。
Objective To investigate the CT classification of localized glandular adenomyosis (GBA) and its clinical significance. Methods The clinical and imaging data of 38 patients with localized GBA confirmed by pathology were collected, including 23 males and 15 females, with an average age of 57 years. All patients underwent multi-slice spiral CT (MSCT) plain scan and multi-phase enhanced scan. The original data were reconstructed by CT thin layer and multiplanar reconstruction (MPR). The localized GBA was classified according to CT findings. Results In 38 cases of localized GBA, there were 9 cases of basilar type. The capillaries at the bottom of the gallbladder were mildly thickened with cap, Thickening at the bottom of the papillary to the convex bulge; mixed type in 2 cases, the bottom of the thickening at the same time to the cavity, the outer ridge. Various types of cases in the plain scan and multi-phase enhanced scan can be seen in the thickened wall distribution of multiple sizes of Luo - A sinus (RAS). Conclusions The CT type of localized GBA is expected to provide a reference for the clinical treatment and surgical options.
