Imaging plays an important role in the evaluation of patients presenting with possible
myositis, with magnetic resonance imaging the most appropriate modality but ultrasound
also playing a complementary role. This article reviews the imaging appearance of
the inflammatory myopathies, other forms of myositis, and mimickers of myositis, with
a discussion of distinguishing features for each entity. The fascia and disease processes
that preferentially involve the fascia are also reviewed.
