Ct and/pelvis contrast for lymphadenopathy. multiple non enlarged retroperitoneal lymph nodes visualized. do you always see these nodes on ct? normal?

These lymph nodes: may not mean anything, unless there is a readily diagnosed condition that will explain their existence, such as acute infection or tumor. Lymph nodes can pop in and out, without rhyme or reason. The existence of CHRONICALLY enlarging lymph nodes would be a red flag. Periodic followup CTs at intervals of 3 or 6 months would be recommended here.
