A rare case of intussusception in an adult caused by a small intestinal inflammatory fibroid polyp

Described here is a case of small bowel obstruction secondary to ileo-ileal intussusception of a rare aetiology in a 34-year-old female presented with acute abdominal pain and vomiting. Ultrasound scan of her hepatobiliary system only showed two small gallbladder polyps with no biliary ductal dilatation, gastroscopy showed mild oesophagitis and gastritis in the antrum and endoscopic ultrasound confirmed the two gallbladder polyps and a normal common bile duct. Computed tomography was performed in view of her persistent symptoms and revealed small bowel obstruction. An intraluminal lesion at 110 cm from the ileocaecal valve was palpable intra-operatively and ileal resection was performed. Histological features of the resected lesion confirmed an inflammatory fibroid polyp. A small number of cases reports on adult patients presented with bowel obstruction can be found in the literature and this rare aetiology should be considered as one of the differentials in the diagnostic process in managing this patient cohort.
