Extensive oedema involving the left quadriceps muscle with sparing of the rectus femoris. Oedema is also reaching up to and surrounding the femoral vessels at the level of the lesser trochanter.
Two focal inhomogeneously, peripherally enhancing mass lesions within the lateral aspect of the vastus intermedius (4.5 x 3.2 x 5 cm) and in the vastus medialis/vastus intermedius 1.8 cm in all dimensions. The larger lesion is in contact with the periosteum of the lateral aspect of the midshaft of the femur, but no radiological evidence of invasion.
No evidence of bone marrow oedema or focal bone lesion within the visualised bones.
