【摘要】：目的探讨MSCT对男性胰腺实性假乳头状瘤(SPT)与无功能性神经内分泌肿瘤(NFPNET)的鉴别诊断价值。方法回顾性分析经病理证实的8例男性SPT和11例NFPNET的病例资料,所有患者均行MSCT平扫及动态增强扫描,对病变发病部位、囊变、边界、钙化、动脉期及门静脉期绝对强化值、强化峰值进行分析。结果SPT 2例发生囊变,NFPNET 7例发生囊变,两种肿瘤囊变率差异有统计学意义(P=0.025);SPT动脉期绝对强化值11.7~55.1 HU,门静脉期绝对强化值28.4~70.2 HU,NFPNET动脉期绝对强化值26.2~124.5 HU,门静脉期绝对强化值50.3~110.6 HU,两种肿瘤动脉期和门静脉期绝对强化值差异有统计学意义(P=0.00);SPT强化峰值8例均出现在门静脉期,NFPNET强化峰值7例出现在动脉期,4例出现在门静脉期,两种肿瘤强化峰值差异有统计学意义(P=0.00);两种肿瘤发病部位、有无钙化、包膜是否清晰、是否伴胰管扩张及胰腺萎缩间差异均无统计学意义(P0.05)。结论胰腺MSCT动态增强扫描有助于男性SPT与NFPNET鉴别诊断。
[Abstract]:Objective to investigate the effect of MSCT on male solid pseudopapillary tumor of the pancreas (SPT) and nonfunctioning neuroendocrine tumors (NFPNET) diagnostic value. Methods a retrospective analysis was made in 8 cases of male SPT pathology and 11 cases of NFPNET were collected, all patients underwent MSCT scan and dynamic enhanced scanning, the diseased parts, cysts, boundary, calcification, The arterial and portal venous phase enhancement of absolute value, peak enhancement were analyzed. Results SPT 2 cases of cysts, 7 cases of NFPNET occurred in two cysts, cystic tumor rate difference was statistically significant (P=0.025); SPT 11.7~55.1 HU absolute arterial phase enhancement value, the absolute value of 28.4~70.2 enhancement in portal vein phase HU, NFPNET arterial phase the absolute value of 26.2~124.5 enhanced HU door The absolute value of 50.3~110.6 enhancement in venous phase HU, two tumor arterial and portal venous phase enhanced the absolute value difference was statistically significant (P=0.00); SPT peak enhancement was found in 8 patients in the portal vein, 7 cases appeared NFPNET peak enhancement in the arterial phase, 4 cases appeared in portal venous phase, enhancement peak difference of two kinds of tumor there was statistical significance (P=0.00); two swollen Tumor site, calcification, the envelope is clear, whether with dilatation of the pancreatic duct and pancreatic atrophy and there were no significant difference (P0.05). Conclusion MSCT dynamic enhanced scan is helpful in differential diagnosis of male SPT and NFPNET.
