Case 3. Extended-field-of-view longitudinal (A) and standard longitudinal images (B-D1) show a similar hematoma (but with an irregular shape) (arrows); the adjacent muscles show disruption of the normal pennate appearance. Comparison with the normal side (D2) shows that the gastrocnemius has an edematous appearance, with loss of the pennate appearance
