Synchronous mid-descending colon cancer and jejunal intraluminal lipomas presenting as intussusception: A rare case report

Abstract

Background: Adult intussusception is rare and typically associated with an underlying lesion acting as a lead point. Jejunal lipomas, though benign, can occasionally cause such findings. The synchronous occurrence of a descending colon carcinoma and jejunal lipoma-induced intussusception is extremely uncommon and often detected incidentally.Case Presentation: A 62-year-old male was evaluated for intermittent abdominal pain with history of few episodes of per rectal bleed. Contrast-enhanced computed tomography (CT) revealed a mid-descending colon mass suggestive of carcinoma, along with a coincidental finding of small bowel intussusception. The patient underwent exploratory laparotomy, which confirmed a mid-descending colon tumour and jejuno-jejunal intussusception caused by multiple intraluminal jejunal lipomas. A left hemicolectomy and segmental jejunal resection with primary anastomoses were performed.Conclusion: This case highlights an unusual synchronous presentation of colorectal malignancy and incidental jejunal intussusception due to lipomas. Such findings underscore the value of detailed preoperative imaging and thorough intraoperative assessment, even in the absence of overt obstructive symptoms.
