Background: Pancreatic carcinoma arising from the uncinate process (pancreatic uncinate carcinoma) is relatively rare. We wished to define its clinical manifestations and sonographic findings. Methods: Clinical and sonographic data of eight cases wer

Background: Neurofibromatosis 1 (NF1) has been studied from many viewpoints, but its abdominal involvement has rarely been reported. Sonography (US) is now the initial diagnostic tool for abdominal exploration, which prompted us to determine the clin

Background and methods: We tried to determine the role and problems of gray-scale sonography (US), computed tomography (CT), and color Doppler sonography in the diagnosis of splenic lymphangioma on the basis of our experience with seven adult cases w

The gastroepiploic vein (GEV) may serve as a collateral circulation associated with splenic vein thrombosis. Despite the extensive literature on its computed tomographic and angiographic findings, there is no description of color Doppler findings of
