History: Young male with a small bluish skin discoloration and pain in the elbow.

Imaging Studies:

  • MRI (see below, 1st image)) : T2 weighted axial image shows a typical venous malformation (low-flow vascular birthmark) located superficially just under the skin. The underlying muscle groups appear normal. 
  • Direct contrast injection into the malformation (see below, 2nd image) outlines the small venous anomaly and also demonstrates venous drainage pathways of the lesion.

Diagnosis: VM

Treatment: This lesion can be treated surgically or by percutaneous means (Sclerotherapy). Sclerotherapy was selected in this case and a tiny amount of sclerosant agent was used (see below, post-sclerotherapy image). Good results and no complication.
