Normal (a) anterior posterior, (b) Grashey, (c) Axillary, and (d) Velpeau radiographs of the right shoulder in (Patient 1) a 21-year-old, right hand dominant, female without evidence of acute fracture or dislocation, bony abnormality, or deformity.

Plain radiographs demonstrated no acute fractures or dislocations, without degenerative changes or obvious bony abnormality or deformity (Fig. 1).
Abnormal magnetic resonance imaging of the right shoulder without contrast in (Patient 1) a 21-year-old, right hand dominant, female. (a) Coronal proton density turbo spin echo (TSE) image, (b) axial T1-weighted image, (c) sagittal T1-weighted image, (d) sagittal T2-weighted TSE fat saturated image demonstrating scarring, fatty infiltration, and edema within the infraspinatus muscle reflecting chronic denervation changes.

Magnetic resonance imaging (MRI) without contrast of the right shoulder demonstrated nonspecific scarring, fatty infiltration, atrophy, and edema of the infraspinatus muscle belly reflecting chronic denervation changes (Fig. 2).

Abnormal magnetic resonance imaging of the right shoulder without contrast in (Patient 2) a 45-year-old, right hand dominant, male. (a) Coronal T2-weighted turbo spin echo fat saturated (TSE FS) image, (b) axial proton density (PD) TSE FS image, (c) sagittal T2-weighted TSE FS image demonstrating denervation edema of the supraspinatus and infraspinatus muscles associated with a 4.1 x 2.6 x 3.6 cm paralabral ganglion cyst and superior labrum anterior posterior tear.
