摘　　要：目的:探讨胰腺内异位副脾(IPAS)的CT表现,从而提高对本病的认识能力及诊断水平。方法:搜集经手术病理证实的2例IPAS患者的完整病例资料,结合文献分析其CT表现。结果:2例IPAS均位于胰尾部,1例在动态增强CT扫描各期,IPAS的强化程度与强化方式均与脾脏相似,动脉期为不均匀强化,门静脉期均匀强化,且密度均高于胰腺;另1例表现为动脉期轻度均匀强化,且动静脉期密度均低于胰腺。结论:IPAS多为单发的圆形或卵圆形、边界清晰的实质性肿块,位于胰腺尾部尖端或非常接近胰腺尾部尖端处,在CT增强扫描各期其强化程度与强化方式均与脾脏相似,动脉期表现为不均匀强化等特征均有助于IPAS的诊断。Objective：To discuss the CT findings of intrapanereatic accessory spleen （IPAS） so as to improve the understanding and diagnostic standard. Methods： The elinicai materials of 2 cases with IPAS proved by surgery and pathology were recruited and their CT features were studied accompanied with literature reviewed. Results： Both of the 2 cases with 1PAS bad the mass located at the pancreas tail. The degree and pattern of enhancement were similar to that of spleen in ev ery phase of dynamic enhanced CT in one ease,which showed heterogeneous enhancement in arterial phase and homogene ous enhancement in venous phase. In the other case,mild homogeneous enhancement was showed in arterial phase and its attenuation was lower than that of pancreas both in the arterial and venous phases. Conclasion：IPAS appears as a single, solid, round or oval mass with smooth contour,locating at or close to the pancreas tail. The enhanced degree and pattern were sire ilar to that of spleen in every phase after enhancement,showing heterogeneous in arterial phase,which is helpful in the diag nosis of IPAS.
