Spontaneous Hemoperitoneum From a Ruptured Ovarian Cyst as the Initial Presentation of Aplastic Anemia in an Adolescent Female Patient: A Case Report.

Severe spontaneous hemoperitoneum resulting from a ruptured ovarian cyst is an uncommon but potentially life-threatening condition. Its occurrence as the initial presentation of underlying aplastic anemia is even more unusual, with only a handful of cases reported in the literature. We present the case of a 17-year-old female patient whose first manifestation of undiagnosed aplastic anemia was significant intra-abdominal bleeding from a ruptured ovarian cyst, requiring emergency laparoscopic intervention. Subsequent investigations confirmed aplastic anemia of unknown etiology. The patient is currently receiving immunosuppressive therapy while awaiting an allogeneic bone marrow transplant. In the interim, ovulation suppression has been initiated to minimize the risk of recurrent hemorrhage.
