Conclusion
In our study, PET/CT test was found to be highly beneficial in the
work-up of FUO. It led to the diagnosis in nearly half of the patients
in which a diagnosis could not be established following a thorough
medical evaluation. Moreover, in patients with weight loss and anemia,
PET/CT is most likely to be helpful in reaching the final diagnosis.
Clinicians should be aware of the clinical utility of PET/CT and its
place in the work-up of FUO following the completion of routine testing.
