Clinical presentation
A 54 year old woman was admitted to our hospital due to melena, which had occurred three times in the previous month. A similar bleed had occurred three years earlier without any diagnosis being established at upper gastrointestinal endoscopy, colonoscopy, and enteroclysis. Also, no lesion was found following the current evaluation of upper gastrointestinal endoscopy and colonoscopy. Multidetector computed tomography (MDCT) and reconstructed three dimensional angiography were performed (figs 1, 2).
