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.

Small bowel metastasis from primary lung cancer is rare. We report the case of an unexpected small bowel intussusception caused by primary non-small cell lung cancer, which was primarily detected by 18 fluorine ((18)F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) and computed tomography (CT). A 74-year-old man underwent FDG PET-CT for the diagnostic workup of a lung mass in the left upper lobe. On FDG PET-CT images, intense FDG uptake was observed in the primary lung mass lesion and mediastinal paraesophageal area. Furthermore, unexpected intense FDG uptake was observed in the jejunum along with the findings of intussusception in the proximal jejunum on the CT images of the PET-CT, which suggested jejunojejunal intussusception caused by lung cancer metastasis. The patient underwent an immediate operation, and the histopathologic results of the resected bowel indicated metastatic lesion from adenocarcinoma of the lung.
