Mesenteric Panniculitis Demonstrated on 18F-FDG PET/CT
No full textMesenteric panniculitis is an underdiagnosed inflammatory condition of unknown etiology that involves the mesenteric adipose tissue. Clinical symptoms are not specific (fever, abdominal pain, or nausea), so diagnosis is not simple. We report a case of 48-year-old man with abdominal pain and fever not responsive to antipyretics and antibiotics for 2 months, who underwent an F-FDG PET/CT after a nondiagnostic CT scan. PET/CT has proven to be a useful method for the diagnosis of mesenteric panniculitis in this patient, showing a uniformly high uptake of FDG in the mesenteric adipose tissue of the mesocolon, mesoappendix, mesosigmoid, and mesorectum

Role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography in evaluating breast mucosa-associated lymphoid tissue lymphoma: A case series
No full textMucosa-associated lymphatic tissue (MALT) lymphoma of the breast is an extremely rare disease; its pathogenesis is not clear because of the rarity of disease, and the best diagnostic method has yet to be established. The metabolic behavior of this lymphoma is not still clear because only a few case reports are present in literature describing the possible role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in this field. This report presents 4 cases of women with histologically proven breast MALT lymphoma who underwent 7 18F-FDG PET/CT throughout the course of disease. All patients underwent staging PET/CT showing in all cases an FDG avid lesion corresponding to breast lymphoma; 3 patients underwent 18F-FDG PET/CT also after chemotherapy. Our results suggest that breast MALT lymphomas are 18F-FDG-avid lymphomas. Positron emission tomography/computed tomography showed heterogeneous but high FDG uptake (mean maximum standardized uptake value 7.9), suggesting that it could be part of diagnostic workup and restaging process
Comparison Between 99mTc-Sulesomab and 18F-FDG PET/CT in a Patient With Suspected Prosthetic Joint Infection
No full textDiagnosing prosthetic joint infection is difficult; clinical signs and symptoms, laboratory tests, radiography, and joint aspiration are less sensitive and specific. We report a patient with fever and painful bilateral hip prosthesis, who underwent Tc-sulesomab scan showing moderate tracer uptake at the lateral surface of the right thigh and no signs of prosthesis infection. The F-FDG-PET/CT showed high uptake at the soft tissue of the right hip prosthesis and detected a fistula. Moreover PET/CT discovered an initial bone marrow involvement at the right femur. The subsequent fistulography confirmed the fistula, and the patient underwent definitive fistulotomy successfully
(18)F-FDG PET/CT follow-up of follicular dendritic cell sarcoma
No full textFollicular dendritic cell sarcoma (FDCS) is a rare lymphoid neoplasm which occurs mainly in lymph nodes, especially cervical and mediastinal; it can be difficult to diagnose and often is misdiagnosed. Its pathogenesis is still not clear, like its evolution. We report a case of 60-year-old woman with FDCS of left lateral cervical node followed for almost 10 years, after a left selective neck dissection, who underwent five (18)F-FDG PET/CT. This technique has proven to be an useful method for the management of this patient, mainly for the follow up, detection of relapse and therapy response evaluation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
