Portal tumor thrombus secondary to gastric carcinoma: report of a case with an emphasis on color Doppler ultrasound findings.

We report the case of a 67-year-old woman with portal tumor thrombus (PTT) associated with gastric carcinoma. Abdominal ultrasound (US) revealed a marked thickening of the gastric wall and a mass lesion in the splenic vein. Color Doppler US showed the intraportal mass to be blood flow-poor and revealed a gastroepiploic vein extending from the splenic hilum to the portal confluence, passing behind the peritoneum.
