Abstract A 70‐year‐old woman presented at our hospital with difficulty in raising the left arm. Two months previously, she developed vesicular rash and pain in the left shoulder and was diagnosed with herpes zoster. Muscle magnetic resonance imaging ( MRI ) revealed increased diffusion‐weighted image ( DWI ) signal intensity in the left supraspinatus, infraspinatus, and subscapularis muscles. After steroid therapy, her muscle strength showed complete clinical recovery and a follow‐up MRI showed a remarkable reduction in DWI hyperintensity in the left shoulder girdle muscles. Muscle MRI findings could be useful to diagnose lesions and evaluate progression in cases presenting focal weakness associated with herpes zoster.
