Abstract:
Gastrointestinal stromal tumours (GISTs) only account for a small percentage of gastrointestinal malignancies with a wide range of clinical presentations depending on the location and size of the tumour. Herein, we present the case of a 55-year-old woman with occult gastrointestinal bleeding (GIB) despite imaging and two separate oesophagogastroduodenoscopy colonoscopies. On double-balloon enteroscopy, an oozing diverticular-appearing lesion in the ileum was identified which on laparoscopy was connected to a large pelvic GIST. This case highlights the importance of considering GISTs in patients with occult GIB, as a high index of suspicion is required for diagnosis.
