A hemorrohagic cyst is a functional cyst, which is related to the function of the organ on which it grows, containing blood, defines MedicineNet. Hemorrhagic cysts are often associated with ovarian cysts, explains Today.
Ovarian cysts occur when one of the follicles that produce eggs in a woman's ovaries accumulates too much fluid, forming a cyst that is larger than the one normally formed during a woman's reproductive cycle, states Today. The cyst becomes hemorrhagic when the structure that normally secretes hormones, corpus lutuem, bleeds into the cyst. When this happens, the woman can experience pelvic pain; however, hemorrhagic ovarian cysts usually remain fairly small, and the body eventually dissolves them naturally.
Cysts that don't dissolve naturally can cause complications, such as ovarian torsion and rupture, warns Mayo Clinic. Ovarian torsion occurs when the cysts becomes large enough to twist, pulling the ovary with it. If a large cyst ruptures, it can result in internal bleeding. A cyst that does not go away on its own and continues to grow may require more direct medical information, including surgery. Surgeons can remove cysts without harming the ovary, but for cysts that show signs of cancer, they often perform a hysterectomy, a procedure that removes the ovaries, uterus and fallopian tubes.
