Red blood cell gastrointestinal bleeding scintigraphy. Appearance of the left ovarian vein.

A case report is presented describing visualization of the left ovarian vein during technetium-99m labeled red blood cell (Tc-99m RBC) gastrointestinal scintigraphy. It demonstrates the usefulness of early dynamic images in differentiating the left ovarian vein from activity within the left ureter that may occur secondary to excretion of free technetium. The left ovarian vein may be visualized during Tc-99m RBC gastrointestinal scintigraphy and should not be mistaken for aberrant vasculature.
