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 analyze the MSCT manifestations of solid pancreatic pseudopapillary tumor (SPTP) and compare it with the pathology to improve the understanding of the disease. Materials and Methods The clinical and CT data of 11 patients (12 lesions) with SPTP confirmed by surgery and pathology were retrospectively analyzed. The CT findings were compared with those of surgical pathology. Results mass larger, the largest diameter 4 ~ 13cm (average 6.9cm). Preoperative CT examination of the capsule can be observed, the border more clearly; pathological specimens of two lesions incomplete capsule, a lesion was partially invaded, the remaining lesions complete capsule. Lumps are cystic solid, 5 lesions to solid-based. One case showed calcification in the center of the lesion. Conclusion SPTP has some imaging features, combined with clinical features CT can make a better diagnosis and differential diagnosis.
