Case 1

A 21 year old female presents to her primary care physician for an enlarging right arm mass. Her past medical history is significant for trauma to her right upper arm while playing field hockey 8 weeks prior. Her physical examination is significant for a pulsating mass in the right upper arm. The remainder of the physical exam is unremarkable.

The patient was asked to undergo a right upper extremity ultrasound.
