Abstract

 

Proliferative myositis is a rare pseudosarcomatous inflammatory process. Radiological diagnosis of selflimiting proliferative myositis helps direct appropriate clinical management and avoiding unnecessary surgical excision. We present the ultrasonography, computed tomography, and magnetic resonance imaging findings in a case of proliferative myositis. In this case, malignancy was suspected, and complete excision was performed. A checkerboard-like pattern, a characteristic sonographic and pathological finding of proliferative myositis, was demonstrated by computed tomography in our patient; to the best of our knowledge, this is the first such case in the literature.
