Unusual White-Yellowish Dots in the Colon Reveal a Rare Metabolic Disease

Abstract

Question: A 33-year old Syrian man, known with thrombocytopenia, was admitted to the emergency department because of gastrointestinal bleeding with hemodynamic instability. Emergency gastroscopy was normal and subsequent computed tomographic angiography revealed the presence of splenomegaly and intestinal bleeding at the splenic flexure of the colon owing to a previously unknown arteriovenous malformation. The malformation was embolized with the use of coils. Four days later, during colonoscopy, the site of prior bleeding was identified and showed a large nonbleeding post-embolization ulcer.
