The lesion is located at the middle part of the muscle and measures about 11 cm in long axis. The fluid-equivalent portion of the lesion represents a deep intramuscular haematoma. b Axial FS T2-w TSE image shows an additional strain of the rectus femoris muscle without a tear, depicted as hyperintensity surrounding the central musculotendinous junction at the mid-portion of the muscle (arrow)
