Puerperal ovarian vein thrombosis presenting as rt loin pain and hydronephrosis: report of 2 cases.

Post-partum ovarian vein thrombosis is an uncommon clinical presentation. 90% of cases present as right loin and right iliac fossa pain, within 10 days of the puerperal period. Two such cases that were referred to the Imaging department as suspected appendicitis/ureteric colic are reported. The findings seen on imaging illustrate the difficulty in the clinical and radiological diagnosis of post-partum ovarian vein thrombosis and highlight the need to include it as a differential diagnosis in cases of post partum acute abdomen. Post-partum ovarian vein thrombosis can be accurately diagnosed by appropriate non-invasive investigations to enable early therapy with anti-coagulants and intravenous antibiotics which are the mainstay of treatment. Surgery can be avoided if diagnosis is made early.
