A 66-year-old woman had an episode of pancreatitis with symptoms starting in October 2023. MRI showed an enhancing soft tissue mass along the superior border of the pancreatic body, as well as signal changes in the pancreatic body and the tail consistent with pancreatitis. The 68 Ga-DOTATATE PET/CT demonstrated intense radiotracer uptake within the peripancreatic soft tissue mass, significantly greater than the spleen background. Biopsy of this peripancreatic mass revealed well-differentiated grade 1 neuroendocrine tumor. The body and tail of the pancreas showed diffusely increased 68 Ga-DOTATATE uptake but obviously lower than the peripancreatic neuroendocrine tumor, consistent with pancreatitis.
一位 66 岁女性于 2023 年 10 月首次出现胰腺炎症状。MRI 显示胰体上缘有一增强的软组织肿块，胰体和胰尾信号改变符合胰腺炎表现。68Ga-DOTATATE PET/CT 示胰周软组织肿块内放射性示踪剂摄取明显增高，明显高于脾脏背景。胰周肿块活检显示分化良好的 1 级神经内分泌肿瘤。胰腺体部和尾部弥漫性摄取 68Ga-DOTATATE 增加，但明显低于胰周神经内分泌肿瘤，符合胰腺炎表现。
