Large vessel arteritis presenting as fever of unknown origin – a clinical case
Keywords:
Arteritis, Fever of unknown origin, Positron emission tomographyAbstract
The authors describe a clinical case of a 55 year-old female patient presenting with fever of unknown origin. The most probable
aetiological diagnosis- large vessel arteritis- was suggested by
positron emission tomography with fl uorodesoxyglicose (PET with FDG).
The role of PET in the non-invasive evaluation of these patients
is highlighted, pointing out the need of a cost-benefi t evaluation
of each laboratory and imaging examination and the selective use of invasive techniques.
The different types of large vessel arteritis as well as their
differential diagnosis are discussed, with reference to a subset
of giant cell arteritis that was described, affecting large vessels
(subclavian, axillary and proximal brachial), with or without simultaneous involvement of the temporal arteries.
