PUERPERAL OVARIAN VEIN THROMBOPHLEBITIS W ITH CLOT PROTRUSION INTO THE INFERIOR VENA-CAVA - EVALUATION WITH US, CT AND MR-IMAGING

Purpose: To assess US, CT, and MR findings in women having puerperal o varian vein thrombosis with dot protrusion into the inferior vena cava . Patients, material et methods: We retrospectively reviewed the duple x US (n = 9), CT (n = 5) and MR (n = 5) examinations of 9 patients wit h 8 right ovarian vein thrombosis, and one left ovarian vein thrombosi s. Results : US findings allowed for the diagnosis of ovarian vein thr ombosis in all patients in showing enlarged tubular echogenic thrombus within the retroperitoneum with clot protrusion in the IVC in all cas es. CT scan and MRI demonstrated ovarian vein thrombosis in all the ca ses in which it was performed but failled to show a mobile thrombus wi thin the IVC in one patient. Conclusion : Duplex US is a reliable tech nique to show puerperal ovarian vein thrombosis and its extension to t he IVC. CT scan and MR imaging can be used to precise the extension to the IVC.
