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.
自发性骨质疏松性骶骨骨折是一种罕见的病症。它们在平片上很难显影。临床上，它们可能会与转移性疾病相混淆。骨扫描上一种特殊的H形摄取模式应提示这种病症，然后CT可以显示骨折情况。在本病例中，放射性核素扫描和CT的这种联合应用使得骶骨骨折与疑似骨转移得以区分。
