Recurrent haemorrhagic ovarian cyst and anticoagulant therapy: a case report with review of treatment modalities.

The common gynaecological causes of acute pelvic pain include ruptured ectopic pregnancy, haemorrhagic corpus luteal cyst or torsion of an ovarian cyst. Ovarian vascular accidents are reported in women on oral anticoagulation presenting as an acute pelvic pain. Although such vascular accidents with anticoagulation therapy are an unusual entity, a meticulous history, clinical examination, and laboratory workup to confirm the diagnosis and timely intervention is needed to reduce attending morbidity and mortality.
