Tongue involvement in a patient with granulomatous myositis.

A 64-year-old woman had difficulty swallowing and talking, weakness of the tongue, and progressive muscle weakness that was proven to be caused by a granulomatous myopathy. This case resembled a motor neuron disease, indicating that granulomatous myopathy should be considered in patients with similar presentations, since it is a treatable condition with a more benign prognosis.
