Leiomyosarcoma of inferior vein cava presenting as acute Budd-Chiari syndrome.

We report a 49-year-old lady who presented with acute Budd-Chiari syndrome. Spiral CT scan showed inferior vein cava (IVC) tumor and ischemia of the right liver secondary to hepatic vein blockage. These were confirmed by MRI scan and IVC gram, at which time tissue diagnosis was obtained. At surgery, the tumor was seen to originate from the infrahepatic IVC and extended to the level of the diaphragm, blocking the hepatic vein outflow. The tumor was excised completely. Histology confirmed it to be leiomyosarcoma of the IVC. The patient is well, without recurrence of symptoms or tumor, 10 months later.
