There is a 14.3 cm (CC) x 1.6 cm (transverse) x 5.2 cm (AP) low T1, high T2 collection between the subcutaneous fatty tissue and underlying fascia located over the greater trochanter of the left femur corresponding to the anechoic collection seen on the ultrasound and a density seen on the left hip radiograph. There is extensive overlying subcutaneous soft tissue edema. The findings are consistent with post-traumatic closed degloving/shearing injury (Morel-Lavallée lesion).
