A 23-year-old man presented with a pre-tibial soft tissue mass. Magnetic re
sonance images demonstrated the subcutaneous, intracortical and intramedull
ary components of an intraosseous venous drainage anomaly, which was confir
med by direct venography. Sclerotherapy using absolute alcohol was subseque
ntly performed under imaging guidance with complete resolution of the subcu
taneous component of the lesion.
