Stomach is a highly vascular organ in the gastrointestinal tract. It is very rare for a stomach to go in for gangrene even in cases of volvulus. Spontaneous gangrene due to acute necrotizing gastritis is a very rare and dreaded condition. This condition is usually not recognized preoperatively due to its rarity. Hence, early diagnosis and prompt expert management are necessary. Here, we present a case of acute necrotizing gastritis which was admitted in our emergency department which was diagnosed to be a case of gastric gangrene preoperatively with the help of radiological investigations.
