Adult intussusception is not uncommon a condition that accounts for only 5% of all intussusception cases. Most of the adult intussusception has a lead point in 70-90% of cases. Presenting symptoms and signs can be non-specific and mostly indicate bowel obstruction, where there is a myriad of causes. Therefore, multiple modalities can be employed to diagnose this condition with CT imaging holds the highest diagnostic accuracy, although other modalities may be adjunct in further management of patient. Herein, we report a case of a 90-year-old gentleman who presented with non-specific symptoms and was eventually diagnosed with sigmoid-rectal intussusception on CT scan, in which prior endoscopic procedure was not able to identify the pathology. This case emphasizes the diagnostic value of CT imaging in diagnosing adult intussusception, particularly in adult patients who present with non-specific abdominal symptoms.
