Maximum intensity projection (MIP) from subsequent SPECT-CT better shows an abnormal focus of radiotracer avidity in the left upper quadrant, towards the splenic hilum, corresponding with previously seen CT abnormality.
There is an incidental focus of additional radiotracer uptake in the right lung base (just above the liver) that demonstrated no anatomic correlate and was felt to be a small benign microclot of Tc-99m sulfur colloid.
Fused SPECT-CT verifies the accumulation of sulfur colloid localises to the indeterminate lesion in the tail of the pancreas, confirming benign intrapancreatic accessory splenule (IPAS).
