摘　　要：【目的】探讨CT在胰腺浆液性寡囊性腺瘤(SOA)与非浸润性黏液性囊性肿瘤(MCN)中的诊断价值。【方法】回顾性分析37例经病理证实为胰腺SOA(18例)或非浸润性MCN(19例)患者的临床及CT影像资料,对两组病例病变发生部位、病变形态、囊腔最大径、囊壁厚度、囊液CT值、壁结节或乳头状突、胰管扩张及钙化进行评价分析。采用t检验、卡方检验、Fisher确切概率法以及Mann-Whitney U检验进行统计分析。【结果】两组病例在病变发生部位、病变形态、囊壁厚度这些方面的差异具有统计学意义(P<0.033)。SOA常发生于胰头颈部(11/18例),病变形态多表现为不规则分叶状(14/18例),囊壁菲薄均匀,平均厚度为(1.1±0.2)mm。而非浸润性MCN多位于胰体尾(14/19例),病变形态多表现为类圆形(14/19例),囊壁厚薄不均,平均厚度为(2.1±1.0)mm。【结论】胰腺SOA与非浸润性MCN在病变发生部位、病变形态及囊壁厚度这些方面各有特点;CT在鉴别诊断胰腺SOA与非浸润性MCN具有一定价值。[Objective] The purpose of our study was to determine useful CT features for differentiating serous oligocystic adenomas （SOA） of the pancreas with noninvasive mucinous cystic neoplasms （MCN）. [Methods] Retrospectively included 37 patients with pathologically proven cystic pancreatic neoplasms： SOA in 18 patients and noninvasive MCNs in 19; location, shape, greatest diameter, thickness of the cystic wall, CT value of the cystic fluid, presence of mural nodules and calcification, dilation of main pancreatic duct were analyzed by CT. T-test, chi-square test, Fisher＇s exact test and Mann-Whitney U test were performed. [ Results ] Significant differences were found in lesion location （P = 0.033）, shape （P = 0.002） and thickness of the cystic wall （P = 0.000） between SOA and noninvasive MCN. SOA located in the head and neck of the pancreas （n = 11 ; 61%）, with lobulated contour （n = 14; 78%） and thin cystic wall （1.1± 0.2 mm）. However, most of the noninvasive MCN arisen in the body and tail （n = 14; 74%） of the pancreas, showed smooth round contour （n = 14; 74%） and the cystic wall were much thicker and uneven （2.1 ± 1.0 mm）. No significant difference was apparent between SOA and noninvasive MCN in other CT features. [ Conclusions ]There are significant characteristic CT features of serous oligocystic adenomas and noninvasive mucinous cystic neoplasms ： location, shape and thickness of the cystic wall could be sensitive features for distinguishing these two lesions.
