71-year-old female with muscle weakness of the right lower extremity. Unable to extend the right lower extremity. Evaluate for denervation. BONE MARROW: Note is made of increased signal abnormality and decreased linear signal abnormality traversing the right femur most consistent with a nondisplaced intertrochanteric insufficiency/stress fracture. No additional bone marrow signal abnormality is identified.SOFT TISSUES: There is heterogeneity and increased signal within the rectus femoris at the level of the myotendinous junction with fluid signal intensity internally suggesting an incomplete tear. Fibers of the rectus femoris can be traced distally to the level of the quadriceps tendon and proximally to the AIIS. There is a 4.5 x 1.3 x 10.0 cm foci of fluid collection adjacent to the rectus femoris which may represent hematoma formation. There is diffuse increased signal abnormality within the quadriceps musculature which is nonspecific and may be posttraumatic in etiology, although subacute denervation cannot be completely excluded and clinical correlation is indicated.There multiple foci of metallic susceptibility artifact along the anterior aspect of the thigh corresponding to surgical clips seen on prior radiographs. There is diffuse fatty infiltration of the imaged musculature.JOINTS: The femoral acetabular joint alignment is anatomic.ADDITIONAL
1. Nondisplaced intertrochanteric insufficiency/stress fracture of the right femur.2. Incomplete tear of the rectus femoris with adjacent fluid collection which is nonspecific but may represent hematoma formation as described above.3. Nonspecific edema type signal abnormality within the quadriceps musculature as described above.These findings were relayed to Luanne Shea by phone at 11:46 AM on 8/28/2015.
