A 35-year-old male felt a painful “pop” in his posterior left lower leg while playing football. Afterward, his “foot didn’t work right anymore.” X-ray of the left ankle and tib/fib was normal but he was unable to ambulate. You plan an ultrasound over the area of maximal tenderness and discover the above image (Image 1.Ultrasound of the left posterior ankle 11cm proximal to the calcaneal insertion of the Achilles tendon.

A 29-year-old male presents with right shoulder pain, throbbing, and swelling. He states that a bulge has appeared over his right anterior shoulder recently (Image 1). While he was doing pushups today, he began to have numbness, tingling, and weakness in his right arm. While in the waiting room, his symptoms have completely resolved.
A 66 year-old man presents with right anterior elbow pain, ecchymosis, and a “lump” in his right upper extremity after a ground level fall (Figure 1). What is your suspected diagnosis? What physical exam maneuver(s) can help you confirm your diagnosis? What is your initial workup in the ED? What imaging confirms the diagnosis? What is your management and disposition?
