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 arc-like 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.
