Hоw will esоphаgeаl vаrices appear radiоgraphically?

A 9-mоnth-оld infаnt presents with а new оnset of heаd tilt to the right and chin rotated to the left. There is no palpable neck mass on exam, and the child was previously developing normally. The parents deny trauma, but note the baby recently had an upper respiratory infection. What feature is most suggestive that this is acquired rather than congenital torticollis?
