There is a fluid-filled defect replacing the adductor longus tendon insertion location. Its tendon shows 15 mm retraction. The myotendinous junction of the adductor longus is normal. There are few tiny fluid clefts with small areas of loss of normal muscle echopattern in the adjacent pectineus muscle. The adductor brevis, adductor magnus, gracilis show normal echopattern.
The contralateral adductors were examined for a comparison, which were normal.
