[Postpartum mesenteric-portal thrombosis of pseudotumor presentation].

Portal thrombosis complicating delivery has not been reported to date. We report on a 28-year-old woman who presented 15 days after abdominal delivery with an abdominal mass. US, color Doppler and CT showed thrombosis of the superior mesenteric and portal veins. Percutaneous thrombolysis was unsuccessful. US and Doppler follow-up showed progressive portal hypertension with recanalization of the left portal vein.
