Venous malformations also enhance on post contrast sequences and may contain phleboliths
presenting as a calcified lesion.
Intramuscular VMs are more likely to present with phleboliths
than malformations of similar size not involving muscle.
Differentiation between calculi and phleboliths
on plain x ray films often poses difficulty but this can be verified on intravenous urography studies where calculi fall in line of the renal system whereas phleboliths
fall outside the line of kidney and urinary bladder.
DISCUSSION: Hemangioma with phlebolith
of the parotid and submandibular glands are frequently seen but hemangioma with phlebolith
in the floor of the mouth is rarely entity.
The patient presented here has the spindle cell type, which is much more specific for Maffucci syndrome (12) and comprised of cavernous vascular spaces with organized thrombi and phleboliths
Plain radiographs and computed tomography imaging can identify phleboliths
or calcified thrombi that are characteristic of cavernous hemangiomas.
In the oral cavity, phleboliths
occur most often on the ventral and lateral borders of the tongue.
In addition, many patients have calcifications that represent vascular phleboliths
(calcified vascular areas) that are not distinguishable from obstructive calculi (Koelliker & Cronan, 1997).
within the pelvis may be confused with a calculus.
25, 39) Fluid-fluid levels and phleboliths
can be seen in slower flow lesions.
The limitations of our study were in diagnosing and detecting these calcifications on OPG since we had to differentiate them with other calcified structures like calcified lymph nodes, the hyoid bone, epiglottis, phleboliths
, submandibular gland sialoloths etc which are commonly found in the region and also some of the calcification may not be calcified enough to be visible on the radiograph.
Magnetic resonance imaging (MRI) of venous malformations may show phleboliths
, calcifications commonly found in venous malformations.
