摘要
目的分析病理证实的阑尾黏液性囊腺瘤(AMC)的临床资料及CT表现.方法回顾性分析2012年05月至2019年12月经病理证实的25例AMC的临床资料,包括病灶位置、大小、形态、囊壁、密度、内部和周边结构.结果21例位于右下腹近回盲部,1例位于右侧结肠旁沟,2例位于右侧盆腔,1例合并肠套叠突入盲肠内;形态为长管形(13例),逗号状(4例),椭圆形(6例),分叶状(1例),梭形(1例);25例病变囊性内容物CT值8.1~39.5Hu;19例壁厚薄均匀,6例壁不均匀;7例囊壁见钙化;2例病变内含积气;6例病变内含分隔;3例病变内含钙化;14例病变周边脂肪间隙清晰,11例周边脂肪间隙模糊.结论AMC的影像学表现为与盲肠相连的囊性肿块,形态多样,囊壁厚薄均匀或不均,可伴钙化、积气和分隔,熟悉这些表现特点有助于提高诊断准确性.
Objective To analyze the clinical data and CT performance of pathologically proven appendiceal mucinous cystadenoma(AMC).Methods We retrospectively assessed a total of 25 cases with AMC collected from May 2012 to December 2019.All lesions were confirmed by pathology.Observation indicators included location,size,shape,cystic wall,density,structure inside and around the lesions.Results 21 lesions were located in the right lower quadrant near the ileocecal part,1 lesion was located in the right paracolic sulci,2 lesions were located in the right pelvic cavity,1 lesion complicated with intussusception into the cecum;the shape was tubal(n=13),comma-shaped(n=4),oval(n=6),lobulated(n=1),fusiform(n=1);the CT value of the content ranged in 25 lesions was from 8.1 Hu to 39.5 Hu;19 cases showed cystic walls with even thickness,6 cases showed cystic walls with uneven thickness;the cystic wall of 7 cases showed calcification;2 showed intracapsular with air;6 showed intracapsular with separation;3 showed intracapsular with calcification;14 lesions with clear stmcture,11 lesions with unclear structure.Conclusion The imaging of AMC is a cystic mass connected with the cecum,the shapes are various,the walls are uniform or nonuniform,the lesions may showed with calcification,air or separation,and learning about these features will contribute to iniprove the diagnostic accuracy of AMC.
