PURPOSE: To evaluate the correlation between computed tomography (CT) and surgery, for the diagnosis of @entity4657 . To analyze the predisposing etiologic factors in this population. @entity1 AND METHODS: We reviewed retrospectively between 1994 and 1999, 12 @entity1 whose final diagnosis was @entity1744 with bezoar. All @entity1 underwent helical CT scan before treatment. Eight @entity1 were treated by surgery and 4 recovered with gastric aspiration. RESULTS: @entity1744 was diagnosed by CT which always demonstrated a transition zone with ovoid intraluminal mass outlined by the bowel wall. The mass consisted of a mixture of soft tissue and internal gas bubbles like feces, suggesting bezoar. Surgery confirmed @entity1744 and presence of bezoar. Predisposing factors were: partial gastrectomy (2/12), post surgical adhesions (7/12), Meckel diverticulum (1/12) and dietary factors. CONCLUSION: We agree with the authors of the few prior CT reports and suggest that the characteristic CT appearance of mottled gas pattern is pathognomonic of bezoar with an excellent correlation in our population.
