We report a case of a 75 year-old man who was diagnosed with a L3-L4 spondylitis with psoas abscess documented at Prevotella denticola. However, the dental origin of the bacteria, the presence of the spondylitis, and the identification on an aneurysm of the inter-atrial septum with a patent oval foramen and finally the metabolic activity of the aortic valve and teeth revealed by 18FFDG PET/ CT ...

Late-life depression (LLD) and Alzheimer's Disease (AD) are the two most frequent neuropsychiatric disorders affecting elderly. LLD and AD may clinically present with depressive and cognitive symptoms. Therefore, when cognitive decline is coupled with depression in the elderly, the differential diagnosis between LLD and AD could be challenging. The aim of the present study was to evaluate in a ...

Fever of unknown (FUO) origin challenges clinical condition. The causes of FUO are diverse: possible etiologies include infectious diseases, chronic granulomatous diseases, malignity, connective tissue disorders and vasculitis. Giant cell arteritis which affects the aorta and its main branches, contributes up to 17% of cases with fever of unknown origin above age 50. There is increasing evidenc...

18F-FDG is formed through radiochemical synthesis from cyclotron-produced 18F (K. Breslow, written communication, June 2000). Production of 18F is through proton bombardment of enriched 18O-water. 18F-fluoride is bound to 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-Dmannopyranose (mannose triflate) under conditions of a stereospecific second-order nucleophilic substitution reaction, whi...

TO THE EDITOR: We read with great interest the recent article by Cheung et al. on the utility of 11C-acetate/18F-FDG PET/CT for clinical staging and appropriate selection of patients with hepatocellular carcinoma (HCC) for liver transplantation based on the Milan criteria (1). The authors of this study were able to show the strength of PET/CT over dynamic contrast-enhanced CT to detect HCCs (pa...

Paget's Disease in the population younger than 50 years is uncommon. We present a 29 year-old male with thyroid cancer and monostotic Paget's Disease of the spine mimicking bone metastases. The patient who was suffering from severe back pain, had increased osteoblastic activity on bone scan consistent with the suspicious lesion defined on MRI and conventional X-ray. Despite the positive radiolo...

Purpose: To determine the value of diffusion-weighted MRI (DWI-MRI) for treatment response assessment in 2-[18F]fluoro2-deoxy-D-glucose (FDG)–avid lymphoma. Experimental Design: Patients with FDG-avid Hodgkin (HL) or non-Hodgkin lymphoma (NHL) at pretherapeutic 18F-FDGPET/CT, who had also undergone pretherapeutic whole-body DWI-MRI, were included in this prospective study. Depending on the hist...

The diagnosis of multiple primary malignancy (MPM) is not uncommon. Nevertheless synchronous MPM involving urinary bladder and hypopharynx is an extremely unusual event.No such cases have been reported so far in English literature to our review. We report the case of 62-year-old male patient who presented with haematuria and later dysphagia to solids. Whole body 18F-fluro deoxy glucose positron...
