Eighteen patients with spondylitis underwent 21 examinations by computed tomography (CT). Bone destruction was found in all, paravertebral inflammatory mass in 18, and epidural extension in 12 examinations. Conventional techniques revealed a paravertebral mass in only two cases. Plain radiographs showed destruction in fewer vertebrae in nine cases, in one of which the plain radiographs were definitely negative. Simultaneous conventional tomography gave sufficient clinical information of bone changes but was not better than plain radiographs in the evaluation of soft tissue structures. Abscesses could only be demonstrated by CT. The operative findings were in agreement with CT scans in almost all cases operated. CT was valuable when planning the surgical approach.
18例脊柱炎患者接受了21次计算机断层扫描（CT）检查。所有患者均发现骨质破坏，18例发现椎旁炎性肿块，12例检查发现硬膜外扩展。传统技术仅在2例中显示椎旁肿块。平片显示9例患者椎体破坏较少，其中1例平片明确为阴性。同时进行的传统体层摄影术能提供足够的骨骼变化临床信息，但在评估软组织结构方面并不优于平片。脓肿只能通过CT显示。几乎所有接受手术的病例，手术所见与CT扫描结果一致。在规划手术入路时，CT很有价值。
