Unusual presentation of intussusception: Gallstone ileus.
Overview
abstract
Gallstone ileus is a rare pathology, occurring in an estimated 0.5% of cases, which preferentially affect females and the elderly population. This rare pathology is the result of a fistulous connection between the bowel and gallbladder. This connection allows gallstones to pass into the bowel leading to mechanical obstruction. On rare occasions the enteric gallstone can act as a lead point causing intussusception. We present a rare case of intussusception secondary to gallstone ileus in a young, relatively asymptomatic patient. CT played a critical role in diagnosis and appropriate management of our patient.
