Symptomatic Meckel's Diverticulum is a rare entity in old patients. The most common complications are gastrointestinal bleeding, intestinal obstruction, acute inflammation, and perforation. Usually those complications occur on the first two decades of life and mostly before the fifth decade. We report an extremely unusual debut of Meckel's Diverticulum, presented as massive spontaneous hemoperitoneum in an 82-year-old man without gastrointestinal bleeding. A literature review of atraumatic hemoperitoneum as presentation of Meckel's diverticulum was made.
