Rare case of entero-enteric intussusception caused by small bowel metastasis from a cardiac liposarcoma

Abstract

Primary cardiac liposarcoma is exceedingly rare and its metastatic potential varies based on the actual tumor subclass. Intestinal intussusception is also an uncommon cause of abdominal pain and bowel obstruction in adults and it usually generates at a malignant lead point in this age group. We report a case of a primary cardiac dedifferentiated liposarcoma in a pregnant woman causing small bowel seeding leading to bowel intussusception.
