Intussusception secondary to squamous carcinoma of the lung.

This report describes unusual radiologic and pathologic findings in a patient with multiple small bowel metastases from squamous cell carcinoma of the lung. The diagnostic work-up revealed a large, pleural-based, right lung mass, a large left adrenal mass, two ulcerated small bowel masses, and a unique giant peduncular mass that caused intermittent intussusception. A pertinent review of the literature is presented.
