91-year-old female with right hip pain. History of breast cancer. Evaluate for fracture. BONE MARROW: No bone marrow signal abnormality is identified.SOFT TISSUES: There is thickening and increased signal abnormality on the fluid sensitive sequences within the right piriformis muscle, particularly along the anterior aspect of the muscle belly along the course of the right sciatic nerve. There is also increased signal abnormality on fluid sensitive sequences within the right iliacus muscle. There is associated enhancement on postcontrast sequences. No focal masslike or nodular enhancement is identified.There is nonspecific peritrochanteric inflammation, right greater than left.JOINTS: Mild to moderate degenerative changes affect the hips bilaterally. There is a small amount of fluid within the hip joints, which is not necessarily of any current clinical significance.ADDITIONAL
1. Enlargement and increased signal abnormality within the right piriformis muscle, particularly along the course of the right sciatic nerve. This constellation of findings has been described in patient's with piriformis syndrome.2. Nonspecific increased signal abnormality within the right iliacus muscle. 3. No acute fracture is evident. Osteoarthritic changes of the hips. Other findings as described above.
