#1 is correct - . Disruption of distal gastrocnemius fibers and superficial ticketing of subcutaneous tissue with fluid collection. Thicken and disrupted facial plane.

This is most likely disruption of the distal gastrocnemius fibers with thickened and disrupted fascial plane

NOTES: Although the images are nice stressing the gastrocnemius and Color or Power Doppler images over the area  of interest could have helped in forming the opinion. The extended field of view (EFOV) helps in evaluating a global view of the affected area. It is always important to get a long axis (LAX) and short axis (SAX).
