18F-fluorodeoxyglucose whole-body positron emission tomography-computed tomography scan maximum intensity projection (after potassium chloride infusion): Altered physiological distribution of 18F-fluorodeoxyglucose with markedly increased uptake in almost all major muscle groups, including those of the neck, thorax, abdomen, and pelvis

The whole-body PET-CT scan demonstrated altered physiological distribution of 18F-FDG with markedly increased uptake in almost all major muscle groups, including those of the neck, thorax, abdomen, pelvis, and the extremities [Figure 1] and reduced uptake in organs that physiologically show much better uptake for example, liver.

It showed normal biological distribution of 18F-FDG [Figure 2] with abnormal increased diffuse heterogonous uptake in enlarged pancreas with adjacent stranding [Figure 3] raising possibility of pancreatitis, and there was a minimal uptake in muscles.
