摘　　要：目的:探讨CT与MRI对儿童胰腺母细胞瘤和实性假乳头状肿瘤的鉴别诊断价值。方法:选取2018年9月至2022年03月术后病理证实的18例儿童胰母细胞瘤和16例实性假乳头状瘤的CT和MR表现。结果:儿童胰母细胞瘤和实性假乳头状瘤的最大轴向直径、边界、钙化、出血、瘤内血管、胰周血管侵犯、远处转移情况及ADC值差异有统计学意义。结论:肿瘤最大轴向直径、边界不清、钙化或出血、瘤内血管、胰周血管侵犯、远处转移及ADC值有助于鉴别诊断儿童胰腺母细胞瘤与实性假乳头状肿瘤。Objective:To investigate the value of CT and MRI in the differential diagnosis of children with pancreatoblastoma(PB)and solid pseudopapillary neoplasm(SPN).Methods:The CT and MR findings of 18 children with pancreatoblastoma and 16 solid pseudopapillary tumors confirmed by pathology from September 2018 to March 2022 were retrospectively analyzed.Methods:The CT and MR findings of 18 children with pancreatoblastoma and 16 solid pseudopapillary tumors confirmed by pathology from September 2018 to March 2022 were retrospectively analyzed.Results:There were significant differences in the maximum axial diameter,boundary,calcification,hemorrhage,intratumoral vessel invasion,peripancreatic vessel invasion,distant metastasis and ADC value between the two groups.Conclusion:The maximum axial diameter of the tumor,unclear boundary,calcification or hemorrhage,intratumoral blood vessels,peripancreatic blood vessel invasion,distant metastasis and ADC value are helpful for the differential diagnosis of PB and SPN.
