Small intestine metastasis from primary lung cancer is uncommon and jejunojejunal intussusception secondary to metastatic lung cancer is extremely rare. We report a case presenting with a one-week history of abdominal pain associated with poor appetite, vomiting and absent defaecation. Physical examination revealed abdominal distention with decreased bowel sounds. Chest roentgenogram showed a mass lesion in the right upper lung zone. Biopsy of the lung mass lesion confirmed adenocarcinoma of the lung. Computed tomography (CT) of the abdomen demonstrated a "target mass" lesion in the right lower abdomen, representing a small intestinal intussusception. Emergency segmental resection of the affected small intestine with jejunojejunal anastomosis was performed. Histological examination of the specimen revealed metastatic adenocarcinoma of lung origin. The patient had an uneventful postoperative course and was discharged home two weeks after surgery.
