Meckel diverticulum is an embryonic remnant of the Gastrointestinal duct which causes symptoms < 5% in the 2% population. Painless bleeding and abdominal pain are the most often reported symptoms. Dieulafoy lesion/dieulafoy-like lesion often cause upper gastrointestinal(GI) tract bleeding, but massive lower gastrointestinal bleeding is rare. We reported a 19-year-old male presented massive lower GI tract bleeding caused by Meckel diverticulum synchronous dieulafoy-like lesion.
