Intestinal intussusception caused by metastatic tumor is uncommon. Symptomatic small bowel metastases from lung cancer have been rarely reported. Here we report a case of intussusception with gastrointestinal bleeding induced by jejunal metastasis of non-small cell lung cancer with a review of the literature. A 52-year-old man was admitted to our hospital because of melena. He had underwent right pneumonectomy and received systemic chemotherapy with radiotherapy for squamous cell lung cancer. Esophagogastroduodenoscopy and colonoscopy failed to reveal bleeding focus. Abdominal CT scan revealed jejunal intussusception and histologic examination of resected jejunum showed metastatic mass from lung cancer. In patients with small bowel obstruction and history of malignancies, possibility of small bowel metastatic tumor should be considered.

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.
