This case report illustrates the role of using neuromuscular ultrasound to diagnose inclusion body myositis (IBM) in a patient who was previously diagnosed with polymyositis. Emerging studies have demonstrated the accuracy of MRI in detecting the selective involvement of the flexor digitorum profundus muscle in those with IBM. However, there have been only few reports on the use of ultrasound in diagnosing this condition. Our case demonstrates the benefit of using this ultrasonographic approach, which is simple, clear, inexpensive, painless and radiation-free, and provides another modality to assist in the evaluation of this sometimes difficult to diagnose condition.
