Association between age, uptake of 18F-fluorodeoxyglucose and of 18F-sodium fluoride, as cardiovascular risk factors in the abdominal aorta. Hell J Nucl Med. 2019 Mar 05;: Authors: Arani LS, Gharavi MH, Zadeh MZ, Raynor WY, Seraj SM, Constantinescu CM, Gerke O, Werner TJ, Høilund-Carlsen PF, Alavi A Abstract OBJECTIVE: We aimed to assess the feasibility of quantifying fluorine-18-fluorodexoglucose (18F-FDG) and 18F-sodium fluoride (18F-NaF) uptake in abdominal aorta and examine their association with age and cardiovascular risk factors. SUBJECTS AND METHODS: Our study comprised 123 subjects (48±14 years of age, 62 men) including 78 healthy volunteers and 45 patients with chest pain syndrome, who originally enrolled in the CAMONA study in Odense, Denmark (NCT01724749). All subjects underwent 18F-FDG positron emission tomography/computed tomography (PET/CT) and 18F-NaF PET/CT on separate days, 180min and 90min after administration of tracers, respectively. The global tracer uptake value (GTUV) in the abdominal aorta was determined as sum of the product of each slice area and its corresponding average standardized uptake value (SUV mean), divided by the sum of those slice areas. In addition, for each subject, the 10 years Framingham risk score (FRS) was calculated. The correlations between 18F-NaF and 18F-FDG GTUV with age and 10 years FRS were assessed in all, healthy and patient subjects. RESULTS: There was a significant, positive cor...

In conclusion, enchondroma growth was a rare event and typically occurred at two years follow-up in our series. Given the low risk for malignant transformation, we propose surveillance with plain radiographic follow-up for stable enchondromas every 3-6 months for the first year and then annually for at least three years of total follow-up. The most significant costs savings can be made by limiting MRI imaging in the absence of clinical or radiographic concern. Additional studies are needed to determine the long-term risk of growth or declaration of chondrosarcoma.Level of Evidence: IV. PMID: 31413693 [PubMed - in process]

Authors: Jiang T, Zhao Q, Tian G, Chen X, Wu L Abstract Metastatic retroperitoneal tumors constitute an end-stage disease with poor prognosis that represents a heavy global health burden. The present study aimed to explore the efficacy of irreversible electroporation ablation (IRE) therapy in patients with end-stage retroperitoneal tumors. Between April 2016 and September 2017, three patients with unresectable retroperitoneal malignant tumors were enrolled. Among these cases, ultrasound (US)-guided IRE was palliatively performed for targeting 3 tumors (1 tumor per patient) located around the abdominal aorta. Post-t...

We present the case of a patient with vertebral dissemination from an intracranial GBM without intra-dural space invasion. The patient underwent a gross total tumor removal followed by radiation therapy (RT) with concomitant temozolomide chemotherapy (STUPP protocol).Following the appearance of back pain, patient underwent whole body computed tomography (CT) and spinal magnetic resonance imaging (MRI) scan.Spinal-MRI highlighted multiple vertebral lesions not infiltrating dura mater being confined to vertebral bodies. CT scan demonstrated the absence of other repetitive lesions in both thorax and abdomen. Histological exam...

We present an extremely rare case of a 3-year-old child with a primary carcinoid tumour of the prostate. A 3-year-old boy presented with failure to thrive, constipation, recurrent respiratory tract infections and pain in the genital area. His karyotype was normal and cystic fibrosis and coeliac disease were excluded prior to further investigation. An abdominopelvic CT scan revealed a prostatic mass. Transrectal ultrasound-guided prostate biopsy was therefore performed and pathological examination revealed a carcinoid tumour.

Pancreaticoduodenal artery aneurysm (PDA) is a rare visceral aneurysm and represents 1.5% of all the visceral arterial aneurysms. A 81-year old man was admitted with acute abdominal pain. He suffered 2 previous episodes of pancreatitis and he underwent abdominal aortic aneurysm repair eleven years before.The CT scan revealed a 92 mm aneurysm of inferior PDA artery with pre-rupture signs associated with the celiac trunk obstruction.The patient underwent a selective catheterization and embolization of superior PDA artery with coils, inferior PDA artery with 12 mm Amplatzer and aneurysm sac embolization by Onyx and coils.The ...

ConclusionThe management of PCI may be challenging particularly in the presence of pneumoperitoneum. Complications must be excluded before considering a conservative therapy. Therefore, PCI should be interpreted with relevance to the entire clinical context.
