Key result
Ultrasonography of nodular-type muscular sarcoidosis revealed an initial hypoechoic mass that later developed central echogenicity over a 1-year follow-up.

Ultrasonography can be a valuable tool in detecting and following up nodular-type muscular sarcoidosis lesions.
Serial US may track nodular muscular sarcoidosis evolution; single case leaves open diagnostic criteria and monitoring utility.
Sarcoidosis is a granulomatous multisystem disorder that rarely involves muscle. Although characteristic ultrasound features of nodular-type muscular sarcoidosis have been reported, observations for such lesions at different disease stages are limited. We report ultrasonographic findings for nodular-type muscular sarcoidosis at 3 months and 1 year after the onset of disease in the left medial gastrocnemius muscle of a 35-year-old woman. A hypoechoic mass was initially detected in the involved muscle, and central echogenicity appeared later. It is, therefore, considered that ultrasonography can be a valuable tool in detecting and following up nodular-type muscular sarcoidosis lesions.

Chen et al. (2007) conducted a case report in Nodular-type muscular sarcoidosis (n=1). Ultrasonography was evaluated on Ultrasonographic findings. Ultrasonography of nodular-type muscular sarcoidosis revealed an initial hypoechoic mass that later developed central echogenicity over a 1-year follow-up.
