Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is one of the least invasive and most effective modality in diagnosing pancreatic adenocarcinoma in solid pancreatic lesions, with a higher diagnostic accuracy than cystic tumors. EUS-FNA has been shown to detect tumors less than 3 mm, due to high spatial resolution allowing the detection of very small lesions and vascular invasion, ...
BACKGROUND The aim of this study was to evaluate the degree of agreement among endosonographers for EUS diagnosis of neoplastic versus non-neoplastic pancreatic cystic lesions and the specific type of cystic lesion. METHODS Videotapes of EUS procedures from 31 consecutive cases of a range of histopathologically proven lesions, including mucinous cystic neoplasm, serous cystadenoma, neuroendoc...
The aim of this study is to identify the key computed tomography (CT) imaging findings and clinical characteristics of pancreatic metastases for its differential diagnosis. CT images and clinical features of 18 patients with 36 histopathologically proven pancreatic metastases were retrospectively reviewed. The primary malignancy included non-small cell lung cancer (NSCLC) (n = 7), gastrointesti...
The likeliest explanation for these fatty lesions is that they are produced by pancreatic enzymes which have entered the circulation either directly or via lymphatics. The latter is thought to be the more important route. Abdominal peritoneal lymphatic drainage and transdiaphragmatic lymphatic absorption of abdominal fluid are probably prime factors in the ingress of pancreatic enzymes to the t...
INTRODUCTION With the improved quality and widespread availability of diagnostic abdominal imaging, incidental intra-abdominal lesions (incidentalomas) are being increasingly identified. Our objective was to characterize the clinical features of asymptomatic patients with incidentally discovered pancreatic lesions and to assess the accuracy of preoperative radiologic diagnosis against the final...
Pancreatic tumours are usually very aggressive cancer with a poor prognosis. A limitation of pancreatic imaging techniques is that lesions are often of ambiguous relevance. The inability to achieve a definitive diagnosis based on cytological evaluation of specimens, due to sampling error, paucicellular samples or coexisting inflammation, might lead to delay in clinical management. Given the mor...
