The patient underwent repeated investigations over four hospital admissions across a span of two months. These included upper and lower gastrointestinal endoscopy, video capsule endoscopy as well as CT enterography, without definitive localisation or treatment of the source of bleeding. Finally, a technetium-99m-labelled red blood cell scan demonstrated a ‘blush’ at the proximal transverse colon on delayed imaging. Targeted colonoscopic evaluation showed a subcentimetre angiodysplastic lesion in the corresponding spot at the proximal transverse colon with slow persistent oozing. Endoscopic clips were applied with successful haemostasis. The patient recovered well without further symptom recurrence 5 months postdischarge. We review the literature on colonic angiodysplasias and discuss the diagnostic challenges in obscure gastrointestinal bleeding. ER -
