Radiopaedia calls phleboliths "vein stones," or calcifications that form in the wall of veins. Therefore, a pelvic phlebolith is a growth or mass that forms within the veins located in the pelvic region.
The human pelvis sits between the abdominal area and thighs, and pelvic phleboliths can form anywhere within this area. They are most commonly seen in the lower area of the pelvis and typically develop in large numbers, notes WikiRadiography. Pelvic phleboliths are usually small, round and similar in size. They're often lumped together in clusters and look very similar to renal stones. Doctors can distinguish between pelvic phleboliths and renal stones by considering the size, shape and position of the growths.
New Health Guide states that phleboliths are harmless, but their presence can indicate that a more serious medical condition is present. Individuals with this condition might experience slight pain in the pelvic area, or kidney and bladder discomfort. One cause of pelvic phleboliths is constipation, which can strain bowels and cause problems that can lead to this and other pelvic conditions. Liver disease can also cause growths to occur in the pelvic or abdominal region. Varicose veins, which are veins that are overstressed and dilated, can also cause calcium growths to develop.
