Representative images from serial computed tomography (CT) and ¹⁸F-fluorodeoxyglucose- (FDG-) positron emission tomography (PET) scans showing resolution of the biopsy-proven aggressive B-cell non-Hodgkin lymphoma in a conglomeration of periaortic lymph nodes. (a) CT image prior to diagnosis. (b and c) CT and FDG-PET images (resp.) at time of diagnosis showing interval decrease in size of the mass. (d and e) CT and FDG-PET images (resp.) six months after initial diagnosis, showing resolution of the mass. Arrows denote the location of the mass.
