Patient Data

Extensive muscular and subcutaneous dystrophic calcifications most prominent in the left lateral thigh.
Hyperechoic areas with posterior acoustic shadow projection at the subcutaneous-muscular plane level associated with slight perilesional edema.
Case Discussion
In addition to the clinical and imaging data, the diagnosis was confirmed with a histopathological examination of subcutaneous tissue, which reported ossification accompanied by a mild mononuclear infiltrate.
Although this case represents an isolated radiological finding in striated muscle and left muscle skin (circumscribed calcinosis), under the clinical context, systemic pathology (dermatomyositis) should be considered, which can affect other regions and organs, especially the lungs.
