title: Computed tomography of spontaneous osteoporotic sacral fractures.
abstract: Spontaneous osteoporotic sacral fractures are an uncommon entity. They are difficult to image on plain films. Clinically, they may be confused with metastatic disease. A peculiar H-shaped uptake pattern on bone scan should suggest the condition, and CT can then demonstrate the fracture. In this case this combination of radionuclide scan and CT permitted differentiation of a sacral fracture from presumed bony metastases.
