Abstract

AIM: The aim of this study was to present the computed tomography (CT) appearance of trichobezoars, phytobezoars and other unusual ingested material. MATERIALS AND METHODS: Seven patients diagnosed on CT with bezoars in the stomach or small intestine were reviewed with special attention on the characteristics of the intraluminal mass and the presence of proximal dilatation. RESULTS: There were six women and one man aged 14-81 years. CT was performed because of abdominal pain and a palpable abdominal mass. In none of the cases was the diagnosis suspected clinically. Four patients had a trichobezoar occupying the entire lumen of the stomach. It appeared as a concentric inhomogeneous mass with entrapped air, surrounded by contrast material. In the other three patients the bezoar was confined to the small intestine and was composed respectively of vegetable fibres, ingested toilet paper and an olive stone. The first two had a mottled appearance whereas the last one was small, spherical and well defined. Variable proximal dilatation of the small bowel was present in all three. CONCLUSION: With the increased use of CT in the evaluation of patients with non-specific abdominal pain, it is important to recognize the CT appearance of bezoars, as this diagnosis is often not suspected clinically.
