Pelvic calcification is the accumulation of calcium deposits in the lower abdomen, states the Northwestern College of Chiropractic. Pelvic calcifications such as phleboliths are very common, affecting around 35 percent of individuals over the age of 40. Most pelvic calcifications do not cause any symptoms or problems.
Pelvic calcifications are often incidentally discovered on X-rays taken of the lumbar spine, states the Northwestern College of Chiropractic. The most common types, phleboliths, are stones formed out of deposited calcium salts that develop within the veins in the pelvis. They have no clinical consequences and do not require treatment. They are typically found just above the pubic bone.
