Small intestinal phytobezoars: Sonographic detection

Three cases of small intestinal phytobezoar, suggested by sonography and later confirmed at surgery, are reported. Sonographic findings of bezoar were intraluminal mass presenting as an arclike surface echo casting clear posterior acoustic shadow within the lumen of the dilated small bowel. Compression of the mass with a transducer induced fluid shift around the mass. We propose that diagnosis of bezoars can be suggested on the basis of sonographic findings.
