you shouldn't be worried.
the ultrasound came back fine.
I'm not sure why your son needs to see a neck specialist or to get an MRI scan of the neck if the area is fine.
this sounds most likely to be a reactive lymph node in the neck which can swell up reacting to an infection or inflammation of the neck area or throat
