Print Overview Ruptured spleen Enlarge image Close Ruptured spleen Ruptured spleen The spleen is located just under your rib cage on your left side. A ruptured spleen may release a large amount of blood into the stomach cavity. A ruptured spleen is a medical emergency that occurs as a result of a break in your spleen's surface. Your spleen, situated just under your rib cage on your left side, helps your body fight infection and filter old blood cells from your bloodstream. A forceful blow to your stomach — during a sporting accident, a fistfight or a car crash, for example — is the usual cause of a ruptured spleen. If you have an enlarged spleen, a less forceful trauma might cause rupture. Without emergency treatment, the internal bleeding caused by a ruptured spleen can be life-threatening. Some people with ruptured spleens need emergency surgery. Others can be treated with several days of hospital care.Products & ServicesA Book: Mayo Clinic Family Health BookNewsletter: Mayo Clinic Health Letter — Digital EditionShow more products from Mayo Clinic SymptomsSigns and symptoms of a ruptured spleen include: Pain in the upper left stomach.
