MSCT在实性假乳头状瘤良恶性鉴别诊断中的价值

摘要

Objective:To investigate the value of MSCT to differentiate benign and malignant solid pseudopapillary tumour of pancreas. Methods:The features of 33 cases SPT proved by operation and pathology were analyzed retrospectively. Results:All cases were solitary tumor. The benign group included 24 cases and the mean age was (29.13±11.96) years. In the benign group,21 tumours with complete capsule,3 tumours with incomplete capsule,22 tumours were round or ovoid shape and 2 tu-mours were lobulated or irregular shape. The malignant group included 9 cases and the mean age was (44.22±19.04) years. In the malignant group,3 tumours with complete capsule,6 tumours with incomplete capsule,5 tumours were round or ovoid shape and 5 tumours were lobulated or irregular shape. The difference was statistically significant in age,the tumor morphology and capsule in benign SPT and malignant SPT. There was no significant difference in gender,tumor diameter,the site of tumour,CT value of solid portion and other features. Conclusions:The CT features of benign SPT and malignant SPT have certain charac-teristics. The age of patient,the tumor morphology and capsule play an important role in identification between benign and ma-lignant solid pseudopapillary tumour of pancreas.%目的:探讨MSCT对胰腺实性假乳头状瘤(SPT)良恶性的鉴别诊断价值.方法:回顾性分析经手术及病理证实的33例SPT的临床及影像资料.结果:病变均为单发.良性SPT 24例,平均(29.13±11.96)岁;22例呈圆形、卵圆形,2例呈分叶、不规则形;21例包膜完整,3例包膜不完整.恶性SPT 9例,平均(44.22±19.04)岁;5例呈圆形、卵圆形,4例呈分叶、不规则形;3例包膜完整,6例包膜不完整.年龄、肿瘤形态及包膜情况在良性及恶性SPT间差异有统计学意义(P<0.05);性别、肿瘤直径、位置、实性部分CT值及其他影像学特征在良性及恶性SPT间差异无统计学意义(P>0.05).结论:良性及恶性SPT的CT表现有一定特征性.年龄、肿瘤形态、包膜情况对SPT良恶性鉴别诊断具有一定价值.
