Low flow venous malformation

Case contributed by Dr Angela Byrne


Swelling of forearm.

Patient Data

Age: 14 years
Gender: Female

A number of rounded calcific densities are seen in the proximal forearm with soft tissue swelling. These have appearances consistent with phleboliths and imply an underlying vascular malformation.


A mass with high T2 and mixed T1 signal is seen within which are embedded the phleboliths seen on plain films. Features are consistent with a low flow venous malformation. 

Case Discussion

Low flow venous malformation in the forearm of a 14-year-old girl. Note the phleboliths, which are a key clue to the diagnosis.
