Trying out Ultrasound of the Week 2.0.  I’ll give you the clips up front to see if you can make the diagnosis.  Now I know you lack the clinical context, ie the benefit of seeing the patient in front of you.  This will be challenging!  I’ll narrow it down to the head and neck region.  Leave a comment with the diagnosis or your best guess.  Do it for the glory, for the respect, and for the medical education!  I’ll reveal all with the ultrasound of the week in a few days.

At my home institution I’ll reward whoever gets it right first.  Good luck!
