INTRODUCTION: Ovarian vein thrombophlebitis (OVT) is a rare but potentially threatening complication of the postpartum period. Diagnosing it may be of some difficulty especially in case of symptoms mimicking appendicitis or pyelonephritis. EXEGESIS: We report 2 patients with postpartum right OVT. The clinical presentation included high grade fever, and pain, lumbar in one case, of the right flank in the other. Pulmonary embolism complicated both cases. CONCLUSION: Diagnostic and therapeutic management of OVT was transformed by progresses in medical imaging during the 1980's. However, optimal duration of anticoagulant treatment and secondary prevention indications have to be determined.
