I don't know for sure.
However somebody earlier wrote "Fan blade 13 missing at hub with evidence of metal fatigue".
This seems to indicate (at least as a possibility) the root cause of this event was a fan blade broken.
After this, whether the blade itself remained "contained" but something else was triggered (some other piece went off as a result) which in turn caused cabin damage etc, in my opinion is immaterial.
I stand to be corrected!
