Female 55 years old Reason: History of right forearm AVM, tx with laser therapy, now with pain and decreased strength to area History: Pain and muscle weakness to right forearm Within the subcutaneous tissues along the lateral aspect of the proximal forearm at the level of the radial head/neck is a vascular malformation. A questionable feeding vessel appears to arise from the proximal radial artery immediately distal to the bifurcation of the brachial artery. The venous drainage follows deep perforators which eventually drain into the cephalic vein. There is no adjacent edema. The visualized muscles and bones are unremarkable. No mass lesions are identified.
Vascular malformation in the superficial proximal lateral forearm as described. It is uncertain whether this is arterial or venous in etiology, however there is a possible feeding artery arising proximal radial artery. A diagnostic angiogram can be considered for further evaluation.
