Yes, this was an acquired arterio-venous malformation showing arterialisation of the dermal vessels with a prominent smooth muscle wall.

The patient presented to me about 25 years ago following trauma to her forehead.  I don't recall if this was blunt trauma or an open wound.  I would imagine that this complication would be more likely with a penetrating injury.  The lesion was pulsatile with a thrill, and bruit on auscultation.  It was one of the only times in my career that  I applied a stethoscope to someone's forehead!
