A 12-year-old boy with DM: A. Gottron’s papules (hyperkeratotic, erythematous, flat papules with central atrophy) on the dorsum of the metacarpophalangeal and interphalangeal joints; B, C, D. Initially, coronal T2-weighted TIRM WB-MRI shows characteristic diffuse, edema-like muscle involvement of several muscles, including tiny areas in the right shoulder, latissimus dorsi and greater trochanter; E, F. MRI performed 3 years later shows significant progression with the involvement of the neck muscles, whole limbs, back and pelvis; G, H. Ultrasound of the biceps in transverse (G) and longitudinal views (H) shows diffusely increased echogenicity and blurred fibrillar echotexture of the muscle, and thickened fascia (parents of the child did not administer the recommended medication)

Ultrasound of the thenar eminences. The left part of the image shows subcutaneous edema of the thenar eminence in the right hand with atrophy of the superficial head of the flexor pollicis brevis (arrow is pointing to the flexor pollicis longus tendon). The right part of the image presents the normal left hand
