Figure 20b. Ovarian vein leading to a pelvic-abdominal mass in a 32-year-old woman. CT scans (a obtained superior to b) show a dilated right ovarian vein, which can be tracked to the posterolateral aspect of a large cystic mass, where it appears to merge with the mass. There are no recognizable features of the suspensory ligament through which the vein passes. The tumor proved to be a mucinous intraepithelial carcinoma arising from the right ovary.
