Miley Cyrus Hospitalized ... For Weird Wrist Injury

According to our sources, Miley had a simple outpatient procedure to remove a cyst that had been giving her problems for sometime. We're told it's a one-time thing and will not require any additional procedures.

Miley Cyrus was hospitalized Friday night for what looks like some kind of weird flesh wound on her wrist ... and she quickly posted pics of the injury -- with a twist.

The 22 year-old singer snapped a photo in an L.A. ER, presumably of the wound -- but just like the rest of her Instagram ... she photoshopped a happy face.

We're told it was a hospital in Tarzana -- the San Fernando Valley -- and she was there Friday afternoon. We don't know what caused the injury.

Miley also posted a pic of herself wearing the gown and noted how hipster it made her look.
