Identification

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.[1] Phleboliths in the pelvic

Because a phlebolith starts as a blood clot, you may be more likely to have other clots form in your blood vessels. Talk to your doctor about whether taking daily aspirin would be a safe and

CT scan In an X-ray image, phleboliths look like rounded white or light-colored spots and have a radiolucent (transparent) center, which can help doctors to distinguish them from ureteral stones.

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.

13/2/2020 · Each phlebolith was examined using soft-tissue and bone settings and was also retrospectively pixel mapped. RESULTS: Seventy-nine (66%) of 120 phleboliths revealed radiolucent centers on abdominal radiography. On CT, 119 (99%) of 120 phleboliths failed to

Computed Tomography Scan Computed tomography (CT) plays a limited role for the evaluation of vascular anomalies given the inherent lack of soft-tissue detail with CT, and it results in significant exposure to unnecessary ionizing radiation. 16,22 Although last generation, multidetector CT can be valuable to obtain a tridimensional reformation and assess aneurismal dilatation, bone erosion in

Pelvic phleboliths are calcium or lime masses that form on the walls of veins. Although such masses are most common in the pelvic region, they can grow anywhere. In most cases, they are harmless. At times, they can be a sign of a more serious underlying

Pelvic phleboliths were shown to lack a radiolucent center on routine clinical CT examinations despite their appearance on radiography. A radiolucent center therefore cannot be used to differentiate phleboliths from distal ureteral stones on unenhanced CT in

Phleboliths are small, round calcifications that occur within the veins, usually found in the lower pelvis area. These are exceedingly common and are for the most part not a real concern for your health. Still, if you have phleboliths it might be worth taking note of them.
