A rare case of jejunal Vanek's tumor causing intussusception in an adult: a case report and comprehensive literature overview

Inflammatory fibroid polyp, or Vanek's tumor, is an uncommon benign small bowel tumor and a rare cause of intussusception in adults. This case involves a 62-year-old man with persistent abdominal pain, diagnosed with jejunoileal intussusception. A 4 cm inflammatory fibroid polyp was discovered during surgery, leading to distal jejunal resection. Despite the rarity of adult intussusceptions, they should be considered in abdominal pain diagnoses. The optimal management approach, whether en bloc resection or initial reduction with limited resection, remains debated.
