Long segment filling defect in the distal ileum measuring 30 cm in length, resulting in proximal small bowel obstruction with a diameter of 6.2 cm. Some intervening small bowel loops are collapsed. The large bowel is not distended.
The lesion demonstrates T2 hypointensity and mainly T1 hypointensity. The minimal T1 hyperintensity is unchanged on T1 fat-saturated images. No restricted diffusion. This represents MRI characteristics of hair bezoar.
