Small bowel intussusception caused by multiple intestinal metastases from a giant cell carcinoma of the lung: a case report.

Small bowel obstruction (SBO) due to intussusception in adults is a rare condition. Diagnosis at the time of admission is usually challenging. More often than not, a bowel intussusception in adults is secondary to an organic condition, frequently malignancies. Therefore, a surgical approach is indicated most of the times. We report the case of a forty-nine years old lady presenting with a SBO secondary to small bowel metastases with two ileo-ileal intussusceptions, one of which was missed at initial surgical exploration. A giant cell carcinoma of the lung (GCCL) with small bowel metastases was diagnosed subsequently. The case is presented as well as a brief review of literature.
