Case 1. 44 years old man. a Pelvis coronal contrast-enhanced, fat-suppressed T1- weighted image. Thickening and enhancement of the proximal right sciatic nerve (arrow). Normal contra-lateral side sciatic nerve for comparison (arrow heads). b Coronal fused F-18 FDG PET/CT image demonstrating an area of intense hypermetabolic focal activity in the region of the right lumbosacral plexus, in keeping with nodular neurolymphomatosis. c Maximum intensity projection (MIP) F-18 FDG PET/CT image demonstrating widespread nodal and extra-nodal hypermetabolic foci (arrows). Note that the intense hypermetabolic activity within the brain, kidneys and urinary bladder are normal findings (*)
