ABSTRACT
Spontaneous intraperitoneal hemorrhage from uterine leiomyomas is rarely encountered. The cause of hemorrhage is mainly trauma and torsion of myoma. Massive intraperitoneal hemorrhage from spontaneous rupture of a superficial uterine vein overlying a subserous myoma is extremely rare. A 48-year-old woman complained general weakness, lower abdominal discomfort and lower back pain. On admission to the hospital, hypovolemic shock, severe anemia and ascites were noticed. Ultrasonography and CT scan showed huge pelvic mass and much amount of fluid in the pelvic cavity. During emergent laparotomy, 3,500 mL of blood were drained from the abdominal cavity and a ruptured superficial vein was noted, located on the serosal surface of a fundal myoma. We report one case of massive intraperitoneal hemorrhage and hypovolemic shock due to spontaneous rupture of a superficial uterine vein overlying a subserous myoma.
