title: CT findings of phytobezoar associated with small bowel obstruction.
abstract: The purpose of this study was to evaluate CT findings of phytobezoar associated with small bowel obstruction. We evaluated abdominal CT of 19 patients with phytobezoar. Abdominal CT of 6 patients with small bowel feces was included for the comparison. On CT we analyzed morphological features of phytobezoars such as location, number, size, shape, and the presence or absence of an encapsulating wall. The sites of the phytobezoar were in the jejunum in 12 patients (63%) and the ileum in 7 (37%). The phytobezoars were single in number in 13 patients (68%) and multiple in 6 (32%). The mean short- and long-axis diameters of the phytobezoars measured 3.2 cm (range 2.1-5.2 cm) and 5.2 cm (range 2.2-11.0 cm), respectively. The phytobezoars were ovoid in 9 patients, round in 6, and tubular in 4. On CT, phytobezoars appeared as gas-containing masses in 17 patients (89%) and as a solid mass without gas in the remaining 2 patients (11%). An encapsulating wall was noted in 6 patients (32%). Small bowel feces were much more tubular in shape but did not have encapsulating wall on CT. The CT imaging is useful in making the diagnosis of phytobezoar associated with small bowel obstruction.
