Case Discussion

Right ovarian partially collapsed hemorrhagic cyst with hemoperitoneum and absence of  extra-ovarian lesion favors ruptured corpus luteal cyst.

Negative urine pregnency test and low serum Beta HCG rule out pregnancy.

1 day follow up shows reduction in free fluid and increase the size of the hemorrhagic cyst.
