ABSTRACT
Soleus muscle injuries are frequently unrecognized, representing a common cause of sports inactivity. This is mainly because little is known about the anatomy of the soleus muscle and the clinical manifestations of injury. Unlike other muscles, the soleus muscle has a complex myoconnective structure with three intramuscular tendons, which makes the interpretation of muscle pathologic conditions challenging. Soleus muscle injuries can be acute or chronic and are usually considered to be a minor discomfort by both the patient and the sports medicine physician, leading to a relatively quick return to sporting activity with a high risk for reinjury. The authors review the soleus muscle anatomy and the importance of being familiar with the most frequent locations of injuries, which are fundamental aspects that every radiologist should understand to avoid underdiagnosis. The role of imaging, the clinical manifestations of injuries, and the differential diagnoses are key aspects to know when evaluating posterior leg pain.
