摘要
目的分析胰腺实性-假乳头状瘤(SPTP)的MSCT表现,并与病理学对照,以提高对该病的认识。资料与方法回顾性分析11例(12个病灶)经手术及病理证实的SPTP患者的临床、CT资料,并将CT表现与手术病理结果进行对照。结果肿块体积较大,最大径4～13cm(平均6.9cm)。术前CT检查均可观察到包膜,边界较清晰;病理标本中2个病灶包膜不完整,1个病灶包膜被部分侵犯,其余病灶包膜完整。肿块均为囊实性,5个病灶以实性为主。1例病灶中心出现钙化灶。结论SPTP具有一定的影像学特征性,结合临床特点CT可较好地做出诊断及鉴别诊断。
Objective To evaluate the CT findings of solid pseudopapillary tumor of the pancreas（ SPTP）, and to correlate the imaging appearances with the pathological findings so as to improve the imaging diagnostics of the disease. Materials and Methods Twelve lesions in 11 cases of SPTP proved by pathlogy were analyzed retrospectively. Imaging features were compared with pathological results. Results The tumors were usually quite large with the largest diameters of 4 to 13cm （mean largest diameter is 6.9cm）. All the lesions showed capsules on CT with clear boundary. On pathologic specimens, two tumors were not well encapsulated, one tumor＇s capsule was partially invaded, other lesions were well-encapsulated. All the tumors contained both solid and cystic components and mainly of solid in 5 tumors. Califications were showed in 1 case. Conclusion The solid psedopapillary tumor of pancreas has comparatively characteristic CT features. CT has value in the diagnosis of SPTP combined with clinic signs.
