A calculus in a vein.



a calculus in a vein formed as a result of the invasion of a thrombus, or blood clot, by connective tissue and the deposition therein of calcium salts. The formation of a phlebolith is associated with thrombophlebitis, usually of a varicose vein. The presence of a phlebolith is asymptomatic; a phlebolith of a deep vein is usually detected by roentgenography. A phlebolith does not require treatment.
