[Jejunal volvulus secondary to torsion of a pedunculated subserosal lipoma: CT diagnosis of a rare cause of bowel obstruction].

The authors report a case of a bowel obstruction secondary to jejunal volvulus in relation with the torsion of a large pedunculated subserosal lipoma. To our knowledge, no such case has ever been reported. The differential diagnosis of intra-abdominal fatty tumors and differential diagnosis of such tumors in association with small bowel obstruction will be discussed. Small bowel volvulus secondary to torsion of a subserosal lipoma should be considered when CT shows a large encapsulated fatty tumor in a patient with suggestion of mechanical small bowel obstruction.
