a Axial short tau inversion recovery (STIR) image of both legs demonstrates extensive myositis bilaterally with extensive edema involving all of the calf muscles within the anterior, posterior and lateral compartments. b Diffusion-weighted sequence reveals patchy areas of restricted diffusion throughout multiple muscles in both legs (arrows), also consistent with acute inflammation. Also note associated intermuscular fascial edema
