A 14 years old female was brought to the clinic by her parents for complaints of progressive weakness of the limbs since childhood. She was unable to climb stairs and unable to get up from the ground without support . She also had the tendency to fall occasionally when walking and experienced marked difficulty in running. She had weakness of arms which made it difficult for her to lift heavy objects. She also had weakness of neck and trunk muscles and there was diffuse wasting of the limbs. Her serum CPK level was 623 (N: 24- 190). EMG study was strongly suggestive of a myogenic lesion and the Nerve conduction study was normal. Serum calcium level was also below normal (7.9 mg/dl). Muscle power on examination was moderately reduced in all four limbs, especially proximally. A subsequent muscle biopsy proved the case to be one of polymyositis.
