case_images: MRI of both thighs ((a) T2 tse fat sat axial, (b) T2-tirm-fs coronal, and (c) T2 tse-fs sagittal left thigh) showing a considerable degree of slightly heterogenous relative hyperintensity of the adductor muscles of both thighs (white arrows) as well as the hamstring muscles of the left thigh (yellow arrows) with no gross increased volume of the muscles appearance. These findings raise the possibility of partial atrophy and intrasubstance edema possibly due to the effects of chronic myositis/myopathy with secondary early muscle atrophic changes.

case_images: Magnetic resonance imaging of both thighs showed diffuse signal changes exhibiting hyperintense signal on T2 and STIR sequences involving bilateral adductor groups and posterior compartment muscles of the thighs giving the picture of myositis (Figure 1).
