A 45-year-old lady presented with colicky abdominal pain, distension, vomiting and constipation, which she had since 3 days. There was no history of similar complaints in the past. She had undergone a tubectomy 17 years back. On examination, she was found to be comfortable but she was dehydrated. Her pulse rate was 94 beats per minute, with a blood pressure of 124/70mmHg. Abdominal examination revealed abdominal distension and tubectomy scar. Abdomen was soft, nontender, there was no palpable mass and there was hyperperistalsis. Digital rectal examination did not show the presence of faeces, or blood. Laboratory investigation showed neutrophilic leucocytosis, blood urea-50mg/dl, serum creatinine-0.8mg/dl. Serum electrolytes were within normal limits. A provisional diagnosis of an intestinal obstruction, probably caused by adhesion, was made. Patient was started on anti-biotics, intravenous fluids, and nasogastric decompression. Erect X-ray of abdomen revealed multiple air-fluid filled dilated small bowel loops. Abdominal ultraonography (USG) showed dilated bowel loops. A contrast enhanced computed tomography (CECT) scan [Table/ Fig-1] demonstrated an ileo-ileal intussusception with dilated proximal small bowel loops.Laparotomy revealed an ileo-ileal intussusception [Table/ Fig-2] with a dilated proximal small intestine. It was situated 50 cm proximal to the ileocecal valve. Intussusception was reduced and polyp was noted as lead point of intussusceptum [Table/ Fig-3]. There was no evidence of any other polyps in the rest of the small bowel. We performed a segmental small bowel resection with extracorporeal end-to-end anastomosis. Post-operative specimen [Table/ Fig-4] showed a firm, circumscribed, endoluminal 2x2.5cm polyp. Postoperative course was uneventful.On microscopic examination [Table/ Fig-5], the surface of the polypoid lesion was found to be covered by ulcerated mucosa, proliferating blood vessels, oedema and an eosinophilic infiltrate in a fibrous stroma. Foci of necrosis were noted. Features were those of an inflammatory fibroid polyp (also called as Vanek's tumour). DisCussionAdult intussusception occurs in only 1% of patients suffering from small bowel obstruction and 80% of such conditions are caused by benign tumours. [1,2]. This disease was first described to occur in the stomach by Vanek in 1949 [3]. Recently, a very interesting review of the literature on IFPs was published [4], which included 1000 cases of IFP, in which the characteristic of this disorder, the diagnostic and therapeutic strategies and microscopy have been described carefully. Only 5% of all intussusceptions occur in adults [5]. In 90% of adult cases, predisposing lesions can be found, but in the paediatric population, organic lesions are found in only 10% of the cases. In 63% of cases of small bowel intussusceptions, benign underlying lesions can be found, whereas in 58% of cases of large bowel intussusceptions, a malignant aetiology has to be expected [5].Vanek's tumour is a rare, benign, non-encapsulated lesion, composed ma...
