Musculo soleo accesorio. Presentacion de un caso y revision de la bibliografia

Abstract

The accessory soleus muscle is an uncommon anatomical variant. We report a accessory soleus muscle in a 18-years-old female and we make a review of the literature. The clinical presentation was soft tissue swelling with mild pain in the posteromedial region of the anekle. Ultrasonography shows homogeneous echogenicity consistent with normal-appearing muscle bundles in the appropriate anatomic location. MRI showed a mass with signal characteristics of normal muscle, but in an abnormal location. Awareness of this entity can help the radiologist contribute significantly to the patients care, because accurate radiographic diagnosis can spare the patient more invasive tests such as exploration and biopsy.
