Abstract
Warfarin a coumarin derivative, is commonly used in prevention and treatment of thromboembolic events in various clinical situations.Although a safe drug,its toxicity may result into spontaneous intraperitoneal or ovarian bleed.A case is reported here of a patient who presented with massive haemoperitoneum due to bilateral corpus luteal haemorrhage secondary to warfarine toxicity.She had undergone mitral valve replacement surgery 10 yrs back and was on warfarin . Imaging suggested a pelvic mass mimicking ruptured ovarian tumour. Her PT/INR was 3.5 at the time of admission. Laparotomy revealed massive haemoperitoneum(3Ltr) with bilateral ovarian bleed which is very rare and no such case of bilateral ovarian bleed is traceable in searched literature .
