Small Intestine Intussusception Due to Lung Cancer Metastasis - A Case Report and Literature Review
摘要
Adult intussusceptions are usually caused by definable structural lesions. Cases of lung cancer with metastasis to the small intestine causing intussusception are very rare. We herein report a case of undiagnosed lung cancer presenting with symptoms of abdominal pain and poor appetite. Despite the absence of history of previous abdominal operation, abdominal radiograph revealed small intestinal obstruction. Computed tomography (CT) demonstrated intussusception of the small bowel. Pre-operative chest radiograph revealed a round opacity about 5 cm in diameter in the right upper lobe. At laparotomy, intussusception due to an ileal tumor located approximately 60 cm from the ileocecal valve was noted. Partial small bowel resection was performed. CT-guided lung biopsy conducted after abdominal surgery confirmed the diagnosis of lung cancer that had metastasized to the small intestine, causing intussusception. Despite adjuvant chemotherapy and targeted therapy, the patient eventually died of cancer progression one year after surgery. Relevant literature was retrieved from the PubMed database from 2006 to 2015 using the keywords ＂adult intussusception,＂ ＂lung cancer,＂ and ＂metastasis.＂ There are sixteen cases including our patient. We reviewed the clinical manifestations, image findings, optimal treatment, and prognosis.
