Clinical: 56y/o female with right hip pain radiating to right leg/knee.
Dx:
1. Right-sided ischiofemoral impingement with abnormal soft tissue edema, inflammation, and fluid centered around the right quadratus femoris muscle and right ischiofemoral space.
2. Increased signal within the right sciatic nerve proximal to a region of fluid and inflammation surrounding the nerve near the ischiofemoral space. This is indicative of mild neuritis and likely secondary to the ischiofemoral impingement.
