原始语种摘要: Abstract(#br)Purpose(#br)The estimated prevalence of cryptorchidism in young males is close to 2%. In oncological PET/CT studies, it might be difficult to recognize false-positive 18 FDG uptake due to an ectopic testis.(#br)Materials and methods(#br)In this pilot study, we report on three patients with lymphoma referred for assessment of response to treatment and in whom cryptorchidism was not known at the time of 18 FDG-PET/CT imaging.(#br)Results(#br)In each of these patients, moderate 18 FDG uptake corresponding to an ovoid mass in the inguinal canal was (or could has been) misinterpreted as a lymphoma-involved inguinal lymph node. Clues to avoid misinterpretation are discussed.(#br)Conclusion(#br)Moderate 18 FDG uptake in ectopic testes represents a potential source of false-positive...
