halp!

I swear I remember a scene in an MCU movie with Captain America's frozen body, on a bed or operating table. (I seem to recall it was fairly dimly-lit, blue-toned, and only very brief.) The only remotely similar scene I can find is from the start of Captain America, when the rescuers find Steve's frozen shield.

Was it a deleted scene? Am I just imagining it? Can anyone help?
