[Pseudotumor aspect of ovarian vein thrombosis]

Ovarian vein thrombosis is an unusual puerperal illness (1 in 600 deliveries) which usually recovers spontaneously or under treatment. We report a rare follow-up observation of a puerperal ovarian vein thrombophlebitis, first diagnosed by computed tomography, which evolved to a 6 x 10 cm pseudotumoral cavernoma mass after 18 months.
