| Summary points: | A 59-year-old male presents with peri-umbilical pain localised to the right iliac fossa. Laboratory findings, diagnostic laparoscopy, surgical findings, and patient follow-up are described; images provided. The authors discuss this first-reported case of perforation and haemorrhage of a Meckel's diverticulum leading to the incidental finding of a gastrointestinal stromal tumour (GIST), review Meckel's which is a common congenital abnormality often mimicking other intra-abdominal pathologies, and discuss GIST management strategies. |
