Abstract: Objective:To review the dual-time-point 18F-fluorodeoxyglucose (FDG) positron emission tomography/X-ray computed tomography (PET-CT) imaging for a patient with primary ureteric lymphoma (PUL),and explore the potential ofFDG PET-CT on diagnosis,staging and evaluation of treatment in patients with PUL.Methods:Complete clinical and imaging data of one patient with PUL was reported.The relevant literatures from 1997 to 2016 were reviewed,and the imaging features of uriteric lymphoma were analyzed.Results:The patient presented with microhematuria,a soft-density mass with moderate enhancement in the mid left ureter,and a luminal stenosis with the scope inserted 5 cm into the left stoma,but no mass was found.The patient was pathologically diagnosed as follicular lymphoma (stage IE confirmed by whole body FDG PET-CT).Conclusion:PET-CT may be useful in diagnosis,clinical stage and therapy assessment in patients with PUL.
