Look at dba_extents, depending on the block size of your database you should be able to find which segments are causing the problem. Obviously your 50M is scattered. I am afraid you will end up exporting all segments in this tablespace, drop them and import them back (or drop and recreate the tablespace and import them back) Got this situation before, so let's shake hands...
