a Sagittal STIR, (b) axial SE T1w, and (c) axial SE T2w images of the left leg of a 41-year-old male with myofascial injury of the calf after a skiing accident. MRI demonstrates a fluid collection at the interface between the medial head of the gastrocnemius muscle and the soleus muscle (arrows) with a component of intermediate signal intensity on the T1w image corresponding to blood (asterisks). Note the infiltration of the connective tissue of the muscles adjacent to the collection (arrowheads)
