Triple phase contrast-enhanced computed tomography (CT) of abdomen revealed a well-defined mass lesion of size 40 mm x 47 mm x 48 mm in close relation to the head of pancreas and another well-defined lesion of size 48 mm x 33 mm in segment VII of the right lobe of liver with both lesions showing arterial phase enhancement (Figure 1).

The 68Ga DOTA-NOC PET CT scan [somatostatin receptor (SSTR) PET CT] showed active SSTR expressing lobulated, centrally necrotic mass lesion with intense DOTA-NOC avidity [standardized uptake value (SUV) max-38.2] involving the head of pancreas measuring approximately 43 mm x 50 mm x 48 mm, closely abutting the duodenum and inferior vena cava (Figure 2).

Another active SSTR expressing tracer avid lesion (SUV max-14.7) was noted in segment VII of liver measuring 40 mm x 38 mm, suggestive of metastatic disease (Figure 3).
