Solitary fibrous tumour presenting as intussusception

Abstract

A 49-year-old male with no comorbidities presented with acute colicky lower abdominal pain for one day, alongside three months of intermittent abdominal pain, loose stools, and melena. A contrast-enhanced computed tomography scan revealed an intussusception. During exploratory laparotomy, an ileo-ileal intussusception with a 3 cm polypoid lesion 10 cm from the ileo-caecal junction was found. The intussusception was reduced, followed by ileal resection and anastomosis. Histopathology and immunohistochemistry (positive for STAT6, CD34, Vimentin, and SMA) confirmed a solitary fibrous tumour (SFT) of the ileum. The patient recovered well and was discharged eight days postoperatively. He is on annual follow-up.
