Inclusion body myositis is the most common idiopathic inflammatory myopathy after age 50 and it presents with chronic proximal leg and distal arm asymmetric mucle weakness. Despite similarities with PM, it is likely that IBM is primarily a degenerative disorder rather

      Inclusion body myositis is the most common form of idiopathic inflamma-tory myopathy in patients over the age of 45 (1). IBM may be initially mis-diagnosed as polymyositis (PM), par-ticularly in the early stages of the dis-ease when muscle biopsy findings are nonspecific and the characteristic IBM pattern of weakness is not apparent.
