Discitis Analysis of 43 Cases

目的：椎间盘炎少见，本文报告４３例，旨在提高对该病的认识。材料与方法：综合４所医院经临床诊断为原发性椎间盘炎２８例，继发性椎间盘炎１５例，对其病因、临床和影像学表现进行回顾性分析。结果：Ｘ线平片、断层和ＣＴ的主要表现有：椎间隙变窄，椎体上缘骨质破坏、增生和硬化，椎间盘破坏，但椎体不融合。持续性肠胀气是继发于术后的椎间盘炎的早期、重要征象。结论：充分认识腰椎间隙感染的影像学改变。

Objective: The purpose of this paper is to well recognize the imaging findings of discitis which is an uncommon di sease.Materials and Methods: The imaging findings and etiology of primary discitis (n=28) and secondary discitis (n=15) were analysed retrospectively.Results: The main features in X ray plain film, tomogram and CT scan were presen ted as: Narrowed intervertebral space, bony damage of upper margin of vertebral body, proliferation and sclerosis and discal destruction without vertebral body fusion.
