Inclusion Body Myositis


Inclusion body myositis (IBM) is a rare inflammatory muscular disorder that usually becomes apparent during adulthood. The disorder presents as slow progressive weakness and withering away (atrophy) of the muscles (myositis), especially of the arms and legs. Inclusion body myositis frequently is diagnosed when a patient is unresponsive to therapy prescribed for polymyositis.
