摘      要：The involvement of the small bowel in systemic forms of amyloidosis may be diffuse or very rarely *** cases of focal amyloidomas of the duodenum and jejunum without extraintestinal manifestations have been *** focal amyloidomas consisted of extensive amyloid infiltration of the entire intestinal wall *** barium studies,ultrasound and computed tomography(CT)patterns of diffuse small bowel amyloidosis have been described:the signs are non-specific and may include small-bowel dilatation,symmetric bowel wall thickening,mesenteric infiltration,and mesenteric *** data are available about the positron emission tomography (PET)/CT and magnetic resonance imaging(MRI)patterns of intestinal *** report two cases of small bowel amyloidosis:the former characterized by focal deposition of amyloid proteins exclusively within blood vessel walls of the terminal ileum,the latter characterized by diffuse intestinal involvement observed on MRI and PET/CT studies.
