Do you have old .mdf and .ldf files(not of the day when DB got corrupted)? you might have taken file backup on some storage.... so get it and save it some where on this server.
If yes, just delete the current .mdf and .ldf as the DB is any which ways useless now.
attach the old .mdf and .ldf files and see if that works.... (as the chances are very less).... if not then I'm sorry to say that the DB is gone now.....
