Abstract: We describe a 61-year-old woman with difficulty extending her left ring finger and little finger caused by sarcoid myopathy. Since her symptom temporarily improved with carpal flexion or forearm pronation, we once misdiagnosed her as having dystonia of upper limb. Her symptom gradually worsened and muscle biopsy specimen revealed sarcoid myopathy. Muscle MRI of left forearm showed abnormal signals in the quadriceps femoris and biceps brachii muscles, and area surrounding the flexor digitorum profundus (FDP) and supinator muscles. Treatment with prednisolone was effective and stopped progression of the symptom. Adhesion of supinator muscle and FDP due to inflammation may have caused limited extension of FDP.
