Longitudinal image of the ultrasound at the site of deformity.
It shows a partly hyperechoic lesion containing many tortuous vessels (much less than 6 vessels/cm2 as expected in haemangioma). There was a very slow venous flow in these vessels on Doppler imaging (not shown here).
This is highly suggestive of a venolymphatic malformation, but MRI is suggested to further evaluate this malformation.
