摘要
目的:探讨胰腺巨囊型浆液性囊腺瘤的MSCT特点,提高诊断准确性。方法:13例经手术病理证实为胰腺巨囊型浆液性囊腺瘤的患者,术前行上腹部MSCT平扫及双期增强扫描。结果:13个病灶均为类圆形囊性灶,呈均匀薄壁,轮廓清、欠规则,大部分未见壁结节(12例),其中2例呈外生性生长,最大径2.0～6.5 cm,平均3.3 cm。11例囊内有纤细分隔,3例分隔内可见点状钙化;1例平扫密度较高似实性病灶,余为水样均匀低密度。动态增强扫描示囊壁和分隔轻度强化。3例伴胰管扩张,其中1例病灶内见多发点状钙化,病理证实为恶变。结论:胰腺巨囊型浆液性囊腺瘤具有相对特征性的MSCT表现。
Objective：To retrospectively analyze the multi-slice CT（MSCT） characteristics of pancreatic macrocystic serous cystadenoma,in order to enhance the diagnostic accuracy.Methods：13 cases with surgery and pathology proved macrocystic serous cystadenoma of pancreas,all underwent pre-and post-contrast enhanced MSCT examinations of upper abdomen preoperatively.Results：All of the 13 tumors were oval shaped and cystic,with smooth contour and thin wall,yet without intramural nodule mostly（n=12）,2 cases were exogenous growth.The maximal dimension ranged from 2.0cm to 6.5cm（mean,3.3cm）.Apart from 1 case showing relatively hyper-attenuation similar to solid mass on plain scan,the other showed homogeneous water-like attenuation.11 cases had fine intra-cystic septa,of which,3 cases had dotted calcifications.Mild enhancement of cystic wall and intra-cystic septa were revealed on dynamic contrast enhanced scanning.3 cases had pancreatic duct dilatation.One case had multiple intra-tumoral dotted calcifications proved as malignant on histopathology.Conclusion：Macrocystic serous cystadenoma of pancreas had certain characteristic MSCT manifestations.
