We report the case of a 72-y-old man with recurrent extranodal marginal-zone B-cell lymphoma who underwent dynamic long-axial-field-of-view 18F-FDG PET/CT. In addition to detecting extensive recurrent disease, a review of a maximum-intensity-projection cine derived from the dynamic acquisition demonstrated delayed uptake and excretion from the left kidney, consistent with impaired function. This incidental functional renal assessment supplemented standard anatomic imaging and influenced treatment management. This case highlights the emerging capability of dynamic long-axial-field-of-view 18F-FDG PET/CT to provide renal functional information in oncologic imaging.
