Inclusion Body Myositis in a Middle-Aged Woman With Knee Pain and Weakness: A Case Report
Weakness and osteoarthritis are common concerns for orthopaedic and primary care physicians when caring for aging adults. We describe a 58-year-old woman with a history of Sjogren syndrome and knee osteoarthritis. She presented to our clinic for injection of viscosupplementation in her left knee, and review of her medical records revealed right hand weakness at 7 years after the onset of symptoms. Findings of muscle biopsy and multiple electromyograms revealed inclusion body myositis, primarily affecting the deep finger flexors and quadriceps muscles. On the basis of this diagnosis, physical therapy and supportive care were recommended. The results of the current case show the difficulty of diagnosing inclusion body myositis and why it often remains undiagnosed.
