Abstract:
PURPOSE: To describe CT and ultrasound(US) appearances of phytobezoar in the small intestine. MATERIALS AND METHODS: During the past two years, CT and US scans of six patients with phytobezoars of the small intestine were retrospectively reviewed. All patients presented symptoms of bowel obstruction, and four had a history of gastric surgery. Four phytobezoars were found in the jejunum and two in the ileum at surgery. We evaluated CT and US findings of phytobezoar and compared these with CT images of the removed phytobezoars. RESULTS: In three patients, US studies showed a curvilinear echogenic mass within the lumen of the dilated small bowel, with a clear posterior acoustic shadow. In six, CT scans revealed an intraluminal mass seen as having a thin soft tissue rim at the periphery and numerous aggregated low attenuation areas representing gas in the central portion. CT findings of the specimens were the same as those of phytobezoars in vivo. CONCLUSION: US and CT appearances of small intestinal phytobezoars are sufficiently distinctive to advocate the preoperative routine use of US and CT for diagnosing this entity.
