摘要: 目的：探讨胰腺内分泌肿瘤（NETP）的CT表现及诊断价值。方法：回顾性分析经手术病理证实19例NETP患者的CT表现，运用Fisher精确检验法分别比较不同级别、功能性和非功能性肿瘤与病灶大小之间关系。结果：19例共23个病灶，其中功能性NETP4例，非功能NETP 15例。根据WHO分级，G1级7例，G2级10例，G3级2例。CT平扫完全实性病灶6个，囊实性17个，完全囊性为0个，钙化4个，主胰管扩张10个。低级别肿瘤小于3 cm 72.7%（8/11），高级别肿瘤大于3 cm 83.3%（10/12），两者具有显著性差异（P<0.05）；而功能性肿瘤小于3 cm66.7%（4/6），非功能性肿瘤大于3 cm 82.4%（14/17），同样两者具有统计学意义（P<0.05）。结论：胰腺内分泌肿瘤CT表现具有一定特征性，肿瘤的最大径有助于不同及功能性、非功能性肿瘤的判断，并可指导临床制订治疗方案。Abstract: objective: To investigate the CT appearance and diagnostic value of pancreatic endocrine tumor (NETP).Methods: The CT manifestations of 19 patients with NETP confirmed by surgery and pathology were analyzed retrospectively, Fisher's exact test was used to compare the relationship between different grades, functional and non-functional tumors and lesion size. Results: 19 patients had a total of 23 lesions, including 4 functional NETPs and 15 non-functional NETPs. According to the WHO classification, there were 7 cases of G1, 10 of G2, and 2 of G3. CT scans consisted of 6 completely solid lesions, 17 solid cystic lesions, 0 complete cystic lesions, 4 calcifications, and 10 main pancreatic duct dilatation. Low-grade tumors were less than 3 cm 72.7% (8/11), high-grade tumors were greater than 3 cm 83.3% (10/12), and the two were significantly different (P<0.05), while functional tumors were less than 3 cm 66.% (4/6), non-functional tumors were greater than 3 cm 82.4% (14/17), and both were statistically significant (P<0.05). Conclusion: The CT findings of pancreatic endocrine tumors have certain characteristics. The maximum diameter of the tumor is helpful for the judgment of different grades and functional and non-functional tumors, and can guide the clinical development of treatment plans.
