A 57-year-old man underwent FDG PET/CT to evaluate a mass in the head of the pancreas. The imaged revealed mildly, nonuniformly increased activity in the mass, but the exact location of the activity could not be determined on the low-dose noncontrast CT portion of the study. On subsequent PET/MRI images acquired 60 minutes after the FDG PET/CT study, the increased activity was clearly localized on the cystic wall. The pathological examination showed that the lesion was intraductal papillary mucinous neoplasm of the pancreas with high degree of dysplasia.
一位 57 岁男性因头部胰腺肿块接受 FDG PET/CT 检查。影像显示肿块有轻度、不均匀的活性增高,但在研究的低剂量非增强 CT 部分无法确定活性的确切位置。在 FDG PET/CT 检查后 60 分钟进行的后续 PET/MRI 图像上,活性明显定位于囊性壁上。病理检查显示病变为胰腺导管内乳头状黏液性肿瘤,伴有高度异型增生。
