35-year-old female with a history of sickle cell disease with venoocclusive crisis. Points to the left groin area with severe pain. Unable to bear weight. Severely limited examination secondary to patient motion artifact. There is nonspecific edema within the anterior thigh musculature extending from the level of the femoral neck to the mid femoral diaphysis, extending off of the field of view of this study. There is also edema surrounding the proximal femoral diaphysis as well as increased signal intensity within the medullary space of the proximal femoral diaphysis. These findings could represent bone infarction and sequela of vaso-occlusive crisis. We cannot entirely exclude the possibility of osteomyelitis on this very limited study. Given the aforementioned limitations, we see no findings to suggest avascular necrosis of the femoral head. There is a small amount of fluid within both hip joints, which is within normal limits.
Extremely limited study as described above showing edema within the proximal femoral diaphysis and the surrounding soft tissues, particularly within the anterior compartment musculature of the thigh. These findings likely represent bone infarction / vaso-occlusive crisis with soft tissue edema. Please note that we cannot entirely exclude osteomyelitis in the basis of this study.
