The invagination, or telescoping, of one segment of the colon into another distal segment is the hallmark of the medical disorder known as intussusception. The invaginated portion of the intestines may be propelled forward by peristaltic movements, which may result in bowel blockage, ischemia, and long-term necrosis. The precise cause of intussusception is ambiguous, particularly in cases with no clear lead point. Dysrhythmic contractions and lymphoid hyperplasia are nevertheless linked to the pathophysiology. A 54-year-old male patient arrived at our emergency department after experiencing abdominal pain that had been progressively increasing for the past three days. The patient had a history of previous appendectomy. It was reported that the pain was abrupt and severe and that it grew worse with each meal or drink. During the physical examination, abdominal distension, discomfort, central guarding, and a small palpable mass measuring 3 x 3 cm were identified. Contrast-enhanced CT scans revealed a 7 cm segment intussusception of the terminal ileum into the cecum and ascending colon. Furthermore, the cecum, mesentery, vasculature, and subsequent nodes were all involved in a significant amount of wall edema. During an emergency laparotomy, a terminal ileocolic intussusception was identified. A restricted segmental resection of the terminal ileum was conducted after the adhesiolysis. Subsequently, an end ileostomy was performed. Ileocolic obstructive intussusception is a rare adult condition caused by a mucinous adenocarcinoma. This case provides a unique perspective on the condition. Consequently, physicians must be vigilant for indications of obstructive intussusception in various colon regions that may suggest malignancy.
