Ruptured corpus luteum cyst is a common finding in women of the reproductive age group but spontaneous hemoperitoneum consequent to corpus luteum rupture in woman on oral anticoagulation is unusual entity. A standard algorithm for management is not described and over a period of time these cases have been managed by both surgical as well as conservative approach. Early diagnosis and appropriate therapy significantly reduce morbidity and mortality associated with this condition. We hereby report successful management of ruptured corpus luteal cyst with massive hemoperitoneum due to unmonitored oral anticoagulant intake in view of thromboembolism.
