目的分析胰腺微囊型浆液性囊腺瘤的MRI表现。资料与方法回顾性分析8例微囊型浆液性囊腺瘤的MRI表现。其中男1例,女7例。所有病例均经手术病理证实。结果 8例微囊型囊腺瘤直径为2.2～8.0cm,平均4.1 cm,肿瘤内存在大量微囊(直径<2.0 cm)和间隔而呈蜂窝状外观。5例肿瘤中央见星芒状瘢痕组织。囊内间隔及中央瘢痕出现强化,而肿瘤囊壁薄(<2.0 mm),无强化。结论微囊型浆液性囊腺瘤的MRI表现较为典型,通过MRI检查可作出正确的诊断。
Objective To analyze the MRI findings of pancreatic microcapsules serous cystadenoma. Materials and Methods Retrospective analysis of 8 cases of microcapsules serous cystadenoma MRI findings. There were 1 males and 7 females. All cases were confirmed by surgical pathology. Results The diameter of 8 cases of microcapsule cystadenoma was 2.2 ~ 8.0cm (mean 4.1 cm). There were many microcapsules (diameter <2.0cm) in the tumor and the interval was honeycomb appearance. 5 cases of central tumor seen star-shaped scar tissue. Intercapsular septum and central scar enhancement, while the tumor wall thin (<2.0 mm), no strengthening. Conclusion The microcapsules of serous cystadenoma MRI performance is more typical, by MRI examination can make the correct diagnosis.
