Femoral neck fracture September 11, 2007Posted by tomography in Uncategorized.
The bone scan demonstrates increased activity in the right intertrochanteric region and absence of activity in the right femoral head. The patient had suffered a recent fall, but no plain films of the hip were obtained at that time. Increased activity was also seen in the left femoral neck, consistent with the patient’s history of healed left femoral neck fracture.
The most likely etiologies in the femoral neck of this elderly demented male with a history of prostate cancer would be trauma or osseous metastasis. Plain films confirm the diagnosis of fracture (not shown here). The rightfemoral head has no uptake, most likely on the basis of disruption of the perfusion by the fracture.
