Stage IV non-small cell lung cancer with multiple metastases to the small intestine leading to intussusception: A case report.

Background: Gastrointestinal tract metastasis from lung cancer is rare and compared to small cell lung cancer (SCLC), non-SCLC (NSCLC) is even less likely to metastasize in this manner. Additionally, small intestinal tumors can also present with diverse complications, some of which require urgent intervention.

Case Summary: In this report, we detail a unique case of stage IV lung cancer, where the presence of small intestine tumors led to intussusception.
