Male, 56 years old. Severe left hamstring injury There is edema within and along the periphery of the long head of the biceps indicating a strain. There is mild edema in the adjacent subcutaneous fat, but we see no large hematoma. The short head of the biceps appears unaffected, and the distal tendon inserts on the fibula in a normal fashion. The conjoint tendon proximally also appears intact. The semitendinosus and semimembranosus muscles appear intact as does the remaining musculature of the left thigh. There is a small knee joint effusion. We see no bone marrow signal abnormality.
