Ascending colon carcinoma presenting as ileocecal intussusception in an adult-a case report with review of literature.

Intussusception is telescoping of a proximal segment of gastrointestinal tract within the lumen of another. Intussusception is a common presentation in pediatric population and present with a classic triad of abdominal pain, bloody diarrhea and a palpable mass. However, intussusception in adults is a rare entity accounting for only 5% of the total cases and is the underlying cause for 1%-5% of all the cases of intestinal obstruction. The adult population caters a varied nonspecific symptoms making diagnosis challenging. We present the case of 32-year-old woman who presented with abdominal pain, altered bowel habits and weight loss. The patient's clinical presentation, familial history of colonic malignancy underscores the importance of considering malignancy as the underlying cause. A contrast enhanced computed tomography (CECT) whole abdomen was done to diagnose the condition. The patient underwent right hemicolectomy and had an uneventful postoperative period. Histopathological findings were consistent with mucinous adenocarcinoma of the caecum.
