Figure 1: Maximum intensity projection PET image (a) showing abnormal 18F-FDG accumulation in left hypochondrium (arrows), mid abdomen (broken arrow), and left lower neck (arrowhead). No local recurrent disease was seen (b-d). Axial contrast CT (e), PET (f), and PET/CT (g) images reveal massive solid cystic splenomegaly (arrows) with heterogeneous enhancement and irregularly increased 18F-FDG uptake (SUVmax-7.9). The splenic lesion is also infiltrating the tail of pancreas. Another enhancing 18F-FDG avid (SUVmax-4.1) mass at junction of head and body of pancreas (h-j, broken arrow) was seen. Also noted was enlarged 18F-FDG avid (SUVmax-3.1) left supraclavicular lymphadenopathy (k-m, arrowhead) PET = positron emission tomography, 18F-FDG = 18F-fluorodeoxyglucose, CT = Computed tomography, SUV = Standardized uptake value.
