55-year-old male with weakness, evaluate for tumor or ligamentous injury There is diffuse increased T2 signal and mild enhancement within the visualized portions of the rectus femoris, vastus lateralis, gluteal muscles and the adductor muscles given the field of view amd the extent of which is only partially visualized on this exam. There are no avulsions or discrete tears visualized. The hip joint itself appears unremarkable. The bone marrow signal is within normal limits. Note is made of artifact within the scrotum, likely due to testicular calcification and prior abscess drainage as seen on prior exams.
Edema and enhancement of the muscles of the thigh which is consistent with denervation and changes described on the correlating lumbar MR; however the appearance and changes are non-specific. In the appropriate clinical setting an infectious or inflammatory myositis could not be entirely excluded.
