Nodular Type of Muscular Sarcoidosis: A Case Report

ABSTRACT

Muscular involvement of sarcoidosis is rare and occurs in two forms nodular and myopathic. In the nodular variety, lesions are long and extend along muscle fibers. Axial MR imaging reveals a star-shaped central structure of decreased signal intensity. Sagittal and coronal MR images show three stripes an inner stripe of decreased signal intensity and outer stripes of increased signal intensity. Longitudinal sonography shows an echogenic inner stripe and hypoechoic outer stripes. We report a case of nodulartype muscular sarcoidosis in a 53-year-old man, describing the findings of MRI and ultrasonography.
