title: Multimodality imaging of direct ureteric involvement in non-Hodgkin's lymphoma using PET/CT, CT urography and antegrade CT pyelography.
abstract: Positron emission tomography/computed tomography (PET/CT), CT urography (CTU) and antegrade CT pyelography (ACTP) findings of ureteric involvement in non-Hodgkin's lymphoma (NHL) are presented. PET/CT performed for restaging in a patient with a 2-year history of Stage 4 NHL showed increased 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG) activity in a distended ureteric segment. CTU and ACTP, performed to further evaluate PET/CT findings, demonstrated diffuse, irregular and concentric thickening of the affected ureteric walls, accompanied by severe irregular narrowing of affected ureteric lumen. Tissue sampling using percutaneous CT-guided biopsy revealed NHL involvement of the ureter. To the best of our knowledge, this is the first report of PET/CT, CTU and ACTP findings of ureteric NHL.
