A young woman with a jejuno-jejunal intussusception.

A 27-year-old woman presented at the emergency department, with pain in the epigastric region. Because physical examination, blood results, urine tests and an X-ray of the thorax showed no abnormalities, she was discharged. Twelve hours later, she presented again at the emergency department, with intense abdominal pain. The blood results, an X-ray and ultrasound of the abdomen were now aberrant. A CT of the abdomen showed an extensive intussusception. During an emergency laparotomy, the intussusception of the proximal jejunum was confirmed. Owing to gangrene of the proximal jejunum, a resection was inevitable. A polyp in the resected part of the jejunum was the lead point of the intussusception. This case report shows the challenges of diagnosing an 'intussusception' and gives a short overview of this condition in adults.
