Increased F-18-FDG Uptake in the Spleen and Multiple Lymph Nodes in Dengue Fever

摘要

A 62-year-old man underwent a whole-body FDG PET/CT for annual cancer screening. By an interview, he had an epigastric pain, and his body temperature was 37.0 degrees C on the day. He just came back home from a travel to Southeast Asia 1 week ago and had presented with chill, high fever (temperature, 39.6 degrees C), arthralgia, myalgia, and skin rash a few days before. Dengue fever was diagnosed by detecting dengue virus type 1 genome and antibody to the virus accompanied by thrombocytopenia and leukopenia. PET/CT examination revealed increased FDG uptake in the spleen and multiple lymph nodes.
