68Ga-DOTATOC PET/CT showing an intrapancreatic accessory spleen mimicking a pancreatic neuroendocrine tumor. Contrast-enhanced CT image in portal-venous phase showing the lesion in the pancreatic tail (a). Contrast-enhanced CT image in arterial phase showing the enhancing lesion in the pancreatic tail. The lesion is characterized by mild 68Ga-DOTATATE uptake, more evident in OSEM-DDG (d) and BSREM-DDG (f) images (SUVmax 8.6 and 7.6, respectively) compared with OSEM (c) and BSREM (e) images without DDG (SUVmax 6.4 and 6.2, respectively). The PET volume of the accessory spleen is smaller in OSEM-DDG and BSREM-DDG images (980 mm3 and 814 mm3, respectively) compared with OSEM and BSREM images without DDG (1400 mm3 and 1520 mm3, respectively).
