Right hip pain radiating to the groin with increasing swelling and warmth overlying the right hip in patient with history of avascular necrosis and sickle cell disease, evaluate for osteomyelitis or abscess. Large field-of-view images of the pelvis and bilateral proximal femurs demonstrate diffuse, somewhat heterogenous decreased T1 signal within the bone marrow compatible with diffuse red marrow. No abnormal foci of increased T2 bone marrow signal are identified to suggest bone marrow edema. No fractures are identified. There is no specific evidence of avascular necrosis within the femoral heads such as bone marrow edema, hemorrhage, or subchondral sclerosis. The femoral heads are grossly round without definite subchondral flattening or fracture. No hip joint effusions are identified bilaterally. Increased T2 signal within the anterior soft tissues of the upper right thigh may reflect artifact or mild soft tissue edema. No discrete fluid collections are identified. Postcontrast images are somewhat degraded by motion but do not demonstrate any grossly abnormal enhancement.
1.Diffuse red bone marrow compatible with history of sickle cell disease.2.No specific evidence of femoral head avascular necrosis or osteomyelitis.3.No hip joint effusions.4.Possible subcutaneous edema within the anterior soft tissues of the right thigh, correlate clinically for cellulitis. No abscess.
