A phlebolith is a small local, usually rounded, calcification within a vein. These are very common in the veins of the lower part of the pelvis, and they are generally of no clinical importance. When located in the pelvis they are sometimes difficult to differentiate from kidney stones in the ureters on X-ray. Phleboliths in the pelvic

A phlebolith, also known as a phlebolite, is a “stone” or calcification (a body formed out of calcium) that develops within the wall of a vein. Phleboliths are masses, clots or growths that develop in the wall of a vein and are composed of calcium or lime.
