title: Ileoileal intussusception secondary to an ileal fibroma.
abstract: Intussusception is defined as the telescoping of a segment of the gastrointestinal tract (intussusceptum) into an immediately adjacent distal bowel (intussuscipiens). Intussusception is a relatively rare cause of intestinal obstruction in adults. Unlike in children, a lead point is present in 90% of adult cases. The most common causes of small bowel intussusception are benign, usually hamartomas, lipomas, inflammatory polyps, adenomas and leiomyomas, in contrast to the large intestine where malignant tumors, usually adenocarcinomas, are more common. The clinical presentation of adult intussusception is non-specific with variable manifestations, predominantly those of intestinal obstruction, often making the diagnosis a challenge. The onset of symptoms may be acute, intermittent or chronic. We present a rare case of an ileal fibroma presenting with intussusception. A 43-year-old woman presented to our outpatient clinic with a history of recurrent abdominal pain. The clinical presentation and CT scan findings led to the diagnosis of ileoileal intussusception. Subsequently she underwent laparotomy which revealed an ileal fibroma as the lead point of the intussusception. Surgical exploration remains essential for diagnosis and treatment since in the majority of cases a pathologic lead point is identified. Ileal fibroma is an uncommon benign neoplasm of the small bowel and must be considered in the differential diagnosis for small bowel intussusception.
