Fever Of Unknown Origin

Fever of unknown origin (FUO) was recognized in the 1960s, when it was
defined as a condition of increased body temperature exceeding 38.3°C measured on several occasions and for a period of more than 3 weeks in an immunocompetent patient with no known illness [1]. More recently, FUO has been classified into three groups according to the type of patient: (1) “classical” in the case of non-immunocompromised patients;(2) “nosocomial” in neutropenic patients; and (3) “patients with HIV”
[2]. The four main causes of FUO are infections, malignancies, autoimmune noninfectious diseases, and miscellaneous [3].
Molecular imaging can play an important role in diagnosing FUO,given that in these patients molecular changes usually occur earlier than morphological structural changes [4]. This determines the advantage of functional imaging with PET/CT over CT or MRI [5].
