1. To demonstrate the pertinent venous anatomy of the gastrointestinal tract with the use of annotated diagrams. 2. To describe and demonstrate the CT appearances of venous invasion in gastrointestinal malignancies as a potential pathway of disease spread.  

Venous invasion are associated with high incidence of hepatic metastases. Incomplete resection of tumors with tumor thrombus may result in local recurrences. We will describe the pertinent vascular anatomy of the stomach, small bowel, colon and rectum with help of illustrations. With the use of  transverse and reconstructed CT images, we will demonstrate the appearance of tumor spread through this pathway in a series of pathologically proven cases.

Extramural invasion along the venous route by gastrointestinal malignancies can be subtle and often overlooked on imaging. Familiarity with the imaging features of this pattern of spread on CT can help the radiologist in its detection.
