Abstract

A mushroom bezoar is an unusual type of bezoar and a rare cause of small bowel obstruction, with the only cases being previously described in the foreign literature. Common sites of obstruction are the gastric outlet, the terminal ileum as well as segments of pre-existing gastrointestinal stenosis of various etiologies. Predisposing factors include a high fiber intake, inadequate chewing, gastric hyposecretion and hypomotility, and a previous gastrectomy and vagotomy. Computed tomography has the capability of directly showing the bezoar and displaying the resulting small bowel obstruction. We report a case of incomplete small bowel obstruction in a 38-year-old woman, caused by a mushroom bezoar in the terminal ileum.
