Background. Lung cancer is prone to distant metastasis at an early stage. However, metastasis to the gastrointestinal tract appears relatively rare, although the rates of metastasis within the lungs, to lymph nodes and pleura are high. Case. An 85-year-old man with bloody sputum was admitted to the pulmonology department of our institution. Sputum cytology indicated a diagnosis of adenocarcinoma. He exhibited vomiting and was further examined due to symptoms of ileus. The target sign was observed on computed tomography (CT) and an emergency surgery was performed for suspected intussusception. Intussuscepted portions of the small intestine observed at 90 cm and 160 cm from the ligament of Treitz were resected. A tumor detected at 240 cm from the ligament was also resected. On a histologic examination, identical histology of the 3 lesions indicated a small intestinal metastasis of the lung adenocarcinoma. The patient died from the malignancy on postoperative day 101. Conclusion. We report a case of intussusception due to metastasis of lung cancer to the small intestine. In lung cancer patients exhibiting symptoms of ileus, intussusception due to small intestinal metastasis should be considered, and examination, diagnosis and surgical treatment should be performed forthwith.
