摘要
目的:探讨胰腺实性假乳头状瘤(SPTP)的CT及MRI表现。方法:9例经外科手术后病理组织学证实的SPTP,术前5例进行CT及MRI平扫和增强扫描,4例只进行CT平扫和增强扫描。结果:肿瘤3例发生在胰头颈部,6例发生在胰尾部。直径2～11cm,均含有囊壁的囊实性肿块,囊性、实性成分比例各有不同,肿瘤内伴有不同程度的出血,囊壁与周围组织分界清楚,9例均未见钙化灶。增强扫描肿瘤实性部分及囊壁有强化,动脉期呈轻度强化,静脉期及延迟期呈轻中度强化,延迟期肿瘤实性部分强化体积及程度更大,囊性和实性结构变得清晰,但均低于正常胰腺。结论:SPTPCT及MRI表现具有一定的特征性。
Objective：To explore CT and MRI performance SPTP of the pancreas.Methods：9 patients with SPTP was proved by pathology.Before the surgery,5 cases were given CT and MRI plain and contrast scanning,and 4 cases were only examed with CT plain scanning and contrast enhanced scanning.Results：3 cases of tumor occurred in the cervical part of the pancreatic head and 6 cases in the tail of the pancreatic tail,whose diameters were 2~11 cm.All of these contained mixed solid cystic masses.The proportion of solid component and cystic was different.There were different degrees of bleeding in the tumors.The boundaries of the bursa walls and peripheral tissues were clear,9 cases had no calcification.Aggrandizement could be seen when given enhanced scan to the solid parts of tumors and bladder walls,light aggrandizement in arterial phase,light and moderate aggrandizement in venous phase and lag phase.In lag phase,the volumes and degrees of the solid parts of tumors became larger,cystic and solid structures got clear,but they were all below the normal pancreas.Conclusion：SPTP on both CT and MRI contains certain characteristics.
