halacha - If a bride did not reveal a medical condition before the marriage is it a mekach taus (annuled)

@DonielF in a comment here seem to clame that (by the end of Ketubot) it is written that a marriage can be annuled (as a mekach tous) if the bride (I guess or her father) withheld information about her medical condition (but did reveal her vows, mumim (phisical deformaties) and her virgin status)

If this true?
(If yes is it all medical conditions?
(If not which ones?))
Where is this written?

Thank You
