Calcific myonecrosis and tenosynovitis: sonographic findings with correlative imaging.

We report the sonographic appearance of a case of calcific myonecrosis and tenosynovitis with correlative plain radiography and CT findings. Calcific myonecrosis is a rare complication of previous trauma that presents as a tumor-like calcified mass years after an initial injury, most commonly affecting the anterior compartment of the lower leg. Although the clinical, radiographic, and MRI features of calcific myonecrosis have been well described, to our knowledge the sonographic appearance has not been reported previously in the literature.
