Phleboliths Venous Malformation

They are particularly common in the pelvis where they may mimic ureteric calculi and are also encountered frequently in venous malformations.

Phleboliths venous malformation. Radiography can demonstrate the presence of phleboliths which are typical of venous malformation figure 48 1. Phleboliths are literally vein stones and represent calcification within venous structures. The best clue for identification of a venous malformation is the presence of phleboliths which appear as small low signal intensity foci with all pulse sequences. They are the most common angiomatous lesions and represent up to 7 of all benign soft tissue tumors 2.

Arteriovenous malformations avms are rare vascular lesion in the buccal fat pad bfp. Venous malformations are part of a spectrum of vascular malformations. Fat suppressed t2 weighted and stir images have been shown to exquisitely define the extent of venous malformations 4 14 figs 3 4. Venous malformation is defined as malformations comprised of slow flowing abnormal dilated veins and venous network 1 clinically venous malformations vm are present at birth and tend to grow steadily in proportion to the somatic growth of the child.

One of the important complications associated with these lesions is phlebolith formation within it. Pelvic phleboliths may also be caused by an uncommon condition known as venous malformation which results in abnormal development of veins. Phleboliths are small round lumps of calcium that form in a person s veins. Phleboliths are small blood clots in a vein that harden over time due to calcification.

They often show up as white spots on pelvic x rays and they can be mistaken for kidney stones. Lytic or permeative changes in bone can be seen in arteriovenous lymphatic or venous malformations figure 48 1. There is an association with maffucci syndrome. To the best of authors knowledge there is no medical literature on avm with phlebolith formation in bfp till date.

Soft tissue venous malformations commonly known as soft tissue hemangiomas are a location dependent benign vascular soft tissue tumor.
