摘　　要：目的探讨胰腺实性假乳头状瘤的影像学表现,以提高对其诊断水平。方法回顾性分析手术、病理证实的2例胰腺实性-假乳头状瘤的临床及影像资料。结果 2例均为年轻女性。一例为胰腺尾部囊实性巨大占位,有包膜,以实性为主,增强后动脉期肿块呈不均性强化,邻近结构受压移位;一例为胰头部占位,胰管轻度扩张,MRI:T1WI肿块呈等低信号,T2WI上脂肪抑制像肿块实性部分呈等高信号。增强后动脉期肿块实性部分轻度增强,囊变坏死区无强化。本组2例均未见肝内外胆管扩张。结论 SPTP临床诊断时容易误诊,CT和MRI对诊断SPTP有一定特征,结合临床,可与其它胰腺肿瘤相鉴别。Objective Discuss the imaging diagnosis of Solid Pseudopapillary Tumor of the Pancreas,so as to improve the diagnosis of this disease. Methods Clinical materials and imaging findings of 2 patients with pathology-proved of Solid2Pseudopapillary Tumor of the Pancreas were retrospectively analyzed. Results 2 cases both are young women,1 case is cystic and solid huge space-occupying in tail of pancreas,a capsule,which was mainly solid and had mild to moderate inhomogeneous enhancement during the arterial phased,and adjacent structures are compression and displacement;1 case is space-occupying in head of pancreas,the pancreatic duct is distended lightly,on MRI,SPTP presented hypo intensity signal on T1W Iand solid areas presented isointensity or hyper intensity on T2W Iaxial fat-suppressed T 2-weighted images. Solid part are enhanced lightly during arterial phase,the area of cystoid variation and necrosis are no enhanced. 2 cases have non-dilated bile duct of liver inside and outside. Conclusion SPTP is easy to misdiagnose during clinical assessment,CT and MRI have some characteristics for SPTP,combined with the clinical,which can distinguished from other tumor in pancreas.
