Accessory soleus muscle: a difficult diagnosis: a case report and a review of the literature.

In this article, we report the case of a patient with a symptomatic accessory soleus muscle with an atypical clinical presentation. As the existence of this accessory muscle went unrecognized for a long time, various diagnoses of the patient's condition were made. Initially, the patient was treated for muscle strain and compartment syndrome, but the second MRI revealed the accessory muscle and led to appropriate diagnosis and surgical treatment.
