History and admission findings We report on a 62-year-old male patient with dry cough for 3 months, constitutional symptoms and elevated inflammatory markers. Investigations Despite extensive diagnostics no infectious, malignant or rheumatologic disease could be found. Bronchoscopy with bronchoalveolar lavage showed lymphocytosis. 18-FDG-PET/CT demonstrated increased metabolic activity of the aorta and its primary branches. Diagnosis, treatment and course We diagnosed large vessel vasculitis consistent to a subtype of giant cell arteritis (GCA) without cranial manifestation...

OBJECTIVE: (18)F-FDG PET/CT has proved to be of potential value for early diagnosis of large-vessel vasculitis (LVV), which frequently involves the aorta. However, its role in the follow-up of these patients has not been well established. Our aim was to evaluate the contribution of (18)F-FDG PET/CT in this clinical situation. METHODS: This study included 37 consecutive patients (28 women, 66.5 ± 9.9 years) with an initial (18)F-FDG PET/CT positive for LVV and a mean ± standard deviation follow-up PET/CT of 7...

BACKGROUND: Fever of unknown origin (FUO) and inflammation of unknown origin (IUO) are diagnostically challenging conditions. Diagnosis of underlying disease may be improved by (18)F-fluorodesoxyglucose positron emission tomography ((18)F-FDG-PET). METHODS: Prospective study to test diagnostic utility of (18)F-FDG-PET/CT in a large cohort of patients with FUO or IUO and to define parameters that increase the likelihood of diagnostic (18)F-FDG-PET/CT. Patients with FUO or IUO received (18)F-FDG-PET/CT scanning in addition to standard diagnostic work-up...

The increasing availability and improvement of imaging techniques are deeply influencing diagnosis and work-up of patients affected with vasculitis, particularly those with large vessel vasculitis (LVV). Fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET), especially when integrated with computed tomography (CT), is taking hold as a useful diagnostic technique to examine the aorta and the other large vessels in giant cell arteritis (GCA) with concomitant large vessel involvement (LV-GCA). In this paper we examined the progresses performed in this field in the last twenty years and the evidence available so far according to two different points of view ('pros' and 'cons'), in order to give a comprehensive answer to a still open question about the role of PET/CT in the diagnosis and follow-up of GCA...

Giant cell arteritis(GCA) is a primary granulomatous vasculitis affecting the large and medium sized arteries. We present here a case of GCA with pyrexia of unknown origin (PUO) as the presenting manifestation in the absence of other typical features. On evaluation, the patient had raised inflammatory markers with features of large vessel vasculitis on whole body PET-CT scan. The colour doppler ultrasonography(CDUS) of the temporal arteries showed bilateral halo sign. Since bilateral 'halo sign' is more specific for the diagnosis of GCA, temporal artery biopsy is not mandatory...

Large vessel vasculitis can pose a significant diagnostic challenge. It may be insidious in onset with the only presenting symptoms consisting of constitutional compromise. It may mimic other pathologies and the only serological abnormalities may be abnormal inflammatory markers. Conventional imaging modalities may not be diagnostic. We present a case of large vessel vasculitis that proved a significant diagnostic challenge with diagnosis established on 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) computerised tomography (CT) imaging...

Combined positron emission tomography/computed tomography (PET/CT) is a whole-body imaging procedure, which enables sensitive detection of inflammatory changes. It may be used to simultaneously obtain both precise anatomical and molecular information in order to comprehensively characterize diseases. The glucose analogue (18)F-fluorodeoxyglucose (FDG) represents a universally applicable radiotracer for imaging of inflammatory processes. Its accumulation in tissues can be semiquantitatively characterized by use of standardized uptake values (SUV)...

FDG is a tracer for visualizing glucose metabolism. PET/CT using FDG is widely used for the diagnosis of cancer, because glycolysis is elevated in cancer cells. Similarly, active inflammatory tissue also exhibits elevated glucose metabolism because of glycolysis in activated macrophages and proliferating fibroblasts. Elevated FDG uptake by active inflammatory tissues, such as those affected by arthritis, vasculitis, lymphadenitis, and chondritis, has enabled the diagnosis of inflammatory diseases using FDG-PET/CT...

Large-vessel vasculitis (LVV) is a group of diseases mainly comprised of giant-cell arteritis (GCA), Takayasu arteritis, and a series of rare diseases like Behçet's disease, IgG4-related disease, infectious aortitis, and other unfrequent entities. Besides clinical and laboratory features, Doppler sonography (DS) can assist in establishing the diagnosis. Its diagnostic sensitivity has been evaluated in various studies, most of them, however, in temporal arteritis (TA) respectively in LVV with involvement of the temporal artery...

Large vessel vasculitis and particularly Temporal Arteritis are systemic diseases that may affect the aorta and its major branches, mainly involving extra cranial branches of the carotid artery. We report a 72-year-old man presenting with weight loss, fever and malaise. Positron emission computed tomography (PET CT) showed an extensive inflammation of the aorta and its major branches. Temporal artery biopsy confirmed the presence of vasculitis with granulomas. Treatment with a high dose of steroids had an excellent clinical response...

Takayasu's arteritis (TAK) is a rare, chronic, large-vessel vasculitis (LVV) that predominantly affects aorta, its major branches and the pulmonary arteries. Recent controversial issues in the diagnosis, disease assessment and prognosis in TAK are discussed in this review. In recent years, conventional angiography, the standard method for the initial diagnosis, seems to have been replaced by the new imaging modalities, such as MRI and 18F-FDG-PET. Less invasive techniques (CT/MRI) are now suggested first, compared to conventional angiography, and MRI is preferable to CT with less contrast load/radiation...

OBJECTIVES: This study investigated the incidence and clinical significance of arterial graft-associated uptake of fluorodeoxyglucose in large-vessel vasculitis (LVV). BACKGROUND: The role of (18)F-labeled fluorodeoxyglucose-positron emission tomography/computed tomography ([(18)F]FDG-PET/CT) in the management of LVV remains to be defined. Although [(18)F]FDG uptake at arterial graft sites raises concerns regarding active arteritis or infection, its clinical significance in LVV has never been formally studied...

The increasing availability and improvement of imaging techniques are making a profound impact in the evaluation and management of patients with vasculitis, particularly for those with large vessel vasculitis, and will most likely play an ever more important role in the future. Deep, large vessels can be examined by CT or MRI, while ultrasound is the method of choice for the evaluation of superficial vessels (such as temporal, carotid, and axillary arteries). PET is very sensitive in detecting large vessel inflammation, but it does not delineate the vessel wall...

Various imaging modalities, including color duplex ultrasonography, CT angiography, magnetic resonance angiography, and PET, are emerging as important aids to the diagnosis, staging, evaluation of disease activity and response to treatment in systemic vasculitis. Although large-vessel vasculitis is the main target of imaging, refinement and increasing accuracy of imaging modalities are also providing useful information in the evaluation of medium-vessel and small-vessel vasculitis.

Previous studies reported a 2- to 17-fold higher risk of aortic complications (dilation or dissection) in patients with giant-cell arteritis (GCA). We aimed to determine whether or not GCA patients with large-vessel involvement demonstrated by positron emission tomography with F-fluorodeoxyglucose combined with computed tomography (FDG-PET/CT) have a higher risk of aortic complications. We conducted a retrospective multicenter study between 1995 and 2014. Patients were included if they fulfilled at least 3 American College of Rheumatology criteria for GCA, or 2 criteria associated with extratemporal biopsy-proven giant-cell vasculitis; they underwent at least 1 FDG-PET/CT scan at diagnosis or during follow-up; and the morphology of the aorta was assessed by medical imaging at diagnosis...

A 65-year-old woman with history of sarcoidosis, hypertension, and peripheral vascular disease presented with lower extremity claudication and low left ventricular ejection fraction of 45% on echocardiogram. Further FDG PET/CT revealed hypermetabolic bilateral chest lymphadenopathy and pulmonary nodules in a butterfly-shaped distribution pattern, which was typically seen in patients with sarcoidosis. In addition, abnormal increased radiotracer uptake was present in pericardium, and along the walls of inferior vena cava, aorta, and pulmonary artery, which correlated with delayed enhancement on further cardiac MRI...
