Our goal was to evaluate retrospectively 30 cases of serous cystadenoma (SCA) to determine its main imaging features as well as to discuss the differential diagnosis problems versus the other cystic lesions of the pancreas.
Thirty SCAs were analyzed; they were all benign lesions, proven at surgery. Twenty-three tumors were evaluated with US, 26 with CT, and 5 with MRI.
Three different morphostructural patterns were identified: microlacunar (n = 19), mixed (n = 6), and macrolacunar (n = 5). The diagnosis of SCA, possible in either the microlacunar or the mixed patterns, was achieved in 74% of cases with US (17/23) and in 61.5% with CT (16/26). Among the 19 patients evaluated with both modalities, the joint information allowed a correct diagnosis in 16 cases (84%). The five macrolacunar tumors were undistinguishable from other cystic masses of the pancreas.
The diagnosis of SCA can be considered certain in the microlacunar, likely in the mixed, and not possible in the macrolacunar type.
我们的目标是回顾性评估30例浆液性囊腺瘤（SCA），以确定其主要影像学特征，并讨论与胰腺其他囊性病变的鉴别诊断问题。
分析了30例SCA；它们均为良性病变，手术证实。23例肿瘤接受了超声检查，26例接受了CT检查，5例接受了MRI检查。
确定了三种不同的形态结构模式：微囊型（n = 19）、混合型（n = 6）和大囊型（n = 5）。超声检查在74%的病例（17/23）中可诊断SCA，微囊型或混合型均可；CT检查在61.5%的病例（16/26）中可诊断。在同时接受两种检查的19例患者中，联合信息在16例（84%）中做出了正确诊断。5例大囊型肿瘤与胰腺其他囊性肿块无法区分。
微囊型SCA的诊断可确定，混合型可能，大囊型则无法诊断。
