Proximal muscle weakness can be induced by many diseases, such as muscular dystrophies, inflammatory muscle diseases, andpolymyalgia rheumatica. Differential diagnosis of these diseases is important. The patient had proximal muscle weakness with anormal creatine kinase (CK) level. Our initial diagnosis was polymyalgia rheumatica because the CK level was normal. The patientwas treated with low-dose corticosteroid. However, the muscle weakness did not improve. The diagnosis of polymyositis wasconfirmed by a muscle biopsy. We suggest that if the patient has typical symptoms with normal CK, then evaluations forinflammatory muscle diseases are essential.
