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 of FDG 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.
