Sporadic inclusion body myositis: magnetic resonance imaging and ultrasound characteristics

Ultrasound optimizes EMG muscle selection in a patient with inclusion body myositis: A case report

“…2 The typical ultrasound findings in IBM are selective changes in the muscle echotexture of the deep flexors of the fingers with preservation of the flexor carpi ulnaris and disturbance of the anterior compartment muscles of the leg, rectus femoris and gastrocnemius.
