“…On MR images, the early changes are diffuse whereas later the lesion becomes well circumscribed. In these patients, the clinical history of recent trauma, maturation (zonation) pattern, absence of an expanding mass, and a self-limiting clinical course distinguish this lesion from calcific myonecrosis [4,25]. Dermatomyositis, polymyositis, and other connective tissue disorders frequently involve deposition of calcium in subcutaneous tissue, fascia, and muscle creating lesions that mimic calcific myonecrosis.…”
