BACKGROUND Intracystic infection, in Autosomal Dominant Polycystic Kidney Disease (ADPKD) and in kidneys with multiple cysts, is a diagnostic and therapeutic challenge, as conventional imaging techniques may not discriminate among "complicated" cysts (infection, bleeding, neoplasia), and as the clinical picture may be attenuated, in particular in early(More)
BACKGROUND Integrated PET/CT is widely used in the preoperative staging and prognostic assessment of non-small-cell lung cancer (NSCLC) patients. The aims of this study were to evaluate the prognostic significance of SUVmax of primary tumor in patients undergoing surgical treatment and, in order to minimize technical interferences, to verify whether SUVmax(More)
From 1976 to 1987 on our Nephrological Unit, 57 patients with IgA nephropathy (IgAN) proven by renal biopsies were found. Three of those presented with acute tubular necrosis (ATN) and glomerulitis, without extrarenal predisposing cause in two; and showed, as prominent manifestation, a severe acute renal failure syndrome (ARFS), needing dialytic treatment.(More)
This study describes the diffuse neoplastic conditions that may affect pleural membranes. These include mesothelioma, the most important and common malignancy of pleural origin, and metastatic involvement by carcinomas, lymphomas and thymomas. On the basis of diagnostic imaging, we identify the distinctive features of pleural involvement by each of these(More)
The aim of this study was to evaluate the role of [18F]fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in the staging of Hodgkin’s and aggressive non-Hodgkin’s lymphoma (HL and NHL), comparing it with conventional diagnostic methods, i.e. contrast-enhanced CT and bone marrow biopsy. Sixty-five consecutive patients (30 HL and(More)
Fever of unknown origin (FUO) is a diagnostic challenge for the wide range of possible causes involved. The aim of our work was to evaluate the role of [18F]-fluorodeoxyglucose positron emission tomography computed tomography ([18F]-FDG-PET/CT) in managing patients with classical FUO. Twenty-four consecutive patients (16 women, eight men; mean age, 56.5(More)
OBJECTIVES The aim of our study was to analyze the specificity and sensitivity of integrated positron emission tomography and computed tomography (PET/CT) in detecting nodal metastasis according to histology (adenocarcinoma vs squamous cell carcinoma), and to identify the factors related to false-negative findings. METHODS A retrospective,(More)
Positron emission tomography (PET) in combination with computed tomography (PET-CT) is commonly used to identify malignant lesion in the lung. Despite there being only a few reports in literature, PET-CT imaging may have many advantages in the study of sarcoidosis, being useful in the diagnosis as well as in monitoring the response to treatment. The object(More)
