60-year-old female with right hip pain. Evaluate for occult fracture versus AVN. ARTICULAR CARTILAGE AND BONE: There is serpentine signal abnormality within the right femoral head extending to the femoral head/neck junction consistent with avascular necrosis. No definite subchondral collapse is identified. Additionally, there is a punctate focus of increased signal abnormality within the left femoral head which is nonspecific and may be degenerative in etiology, although, early avascular necrosis cannot be excluded. Degenerative changes affect the imaged lower lumbar spine. There is diffuse heterogeneous bone marrow signal abnormality which is nonspecific but may reflect residual islands of red marrow.SOFT TISSUES: There is diffuse fatty infiltration of the musculature of the right and left hips as well as affecting the paraspinal musculature. ADDITIONAL
Findings consistent with avascular necrosis of the right hip. Other findings as described above.
