Telescoping jejunum: a case of adult intussusception

Intussusception is the invagination of a proximal part of intestine into the adjacent distal part. Reported frequently in children, it forms a rare presentation in adults and can be difficult to diagnose pre operatively. Imaging modalities are increasingly being used for preoperative diagnosis with almost all cases in adults being secondary to an intestinal lesion. Intraoperative management of such lesions in adults was mostly reported to be done by en bloc resection without attempts at reduction, especially where a preoperative diagnosis of a benign lesion was not in hand. We present a case of a female patient with a background of active metastatic lung cancer presenting with symptoms and signs of high intestinal obstruction, found to have a jejunal intussusception on CT scan and managed conservatively initially, followed by definitive surgical management. Literature review of similar presentations, diagnostic and treatment modalities are discussed thereafter.
