Abstract: Objective:To investigate multi-detector CT(MDCT) findings of intestinal obstruction caused by bezoars ileac and improve the levels of diagnosis and differential diagnosis.Methods:The MDCT findings and reconstruction techniques of 30 cases with bezoars ileac which identified by operations were retrospectively analyzed.Results:The accuracy of qualitative and positional diagnosis of intestinal obstruction caused by bezoars ileac were 100%(30 /30) and 90%(27 /30) respectively.Bezoars ileac was mainly showed as round or oval in shape and as relatively low in density,with an average CT value of 60 Hu and without any evidence of enhancement in MDCT.The inner density was abnormal-distributed,appearing in a cribriform pattern asair-bladdersign ormeshworkstructure; a tiny interval filled contrast media between bezoars ileac and bowel wall in delayed enhancement MDCT scanning was also observed.Conclusions:MDCT shows an important clinical value for qualitative and positional diagnosis of intestinal obstruction caused by bezoars ileac.
