Solitary Periaortic Tuberculous Granuloma Mimicking Neoplastic Disease on 18F-FDG PET/CT

Abstract Solitary tuberculoma of periaortic space is extremely rare. We report a case of periaortic tuberculous granuloma revealed by 18 F-FDG PET/CT in a 51-year-old woman without pulmonary or any other organ involvement. Awareness of this rare but possible atypical presentation of tuberculosis is helpful for the differential diagnosis of periaortic mass.
