Intussusception Induced by Cecal Metastasis of Primary Small Cell Lung Cancer

Abstract

Large bowel metastasis from a primary lung cancer is rare and is hard to be asymptomatic. We report a case of intussusception without any symptoms caused by cecal metastasis of primary small cell lung cancer. A 70-year-old woman was admitted to hospital with cough and sputum of 3 weeks’ duration. She was diagnosed with small cell lung cancer based on percutaneous needle biopsy of a lung mass identified by chest CT. In abdominal CT, multiple metastatic lesions were detected in the left adrenal gland and cecum with intussusception. After further colonoscopy and biopsy evaluations, the pathology results showed metastatic cancer originating from small cell cancer of the lung. (Korean J Med 2013;85:218-222)
