2、而椎體結核中后期椎問盤才會有改變;②相鄰椎體骨質(zhì)改變上:椎間盤炎表現(xiàn)為相鄰的上、下兩個椎體的部分或全部對稱性炎性改變.少有椎體骨折.而椎體結核椎體骨質(zhì)多呈蟲蝕樣破壞.常侵蝕多個椎體.常合并病理性骨折;④椎旁軟組織改變上:椎體結核遠比椎問盤炎明顯.椎體結核常侵犯到腰大肌、椎管內(nèi)硬膜外同隙及一側椎間孔.常使椎管狹窄.而椎間盤炎僅表現(xiàn)為椎問盤旁軟組織的輕度腫脹。結論:椎間盤炎與脊柱結核各有其特點.仔細觀察椎間盤、椎體以及椎旁軟組織上的改變.結合臨床已不難鑒別。【關鍵詞】椎間盤炎;脊柱結核;鑒別診斷;磁共振成像中圖分類號:R68l;R445.2文獻標識碼:A文章編號:1006—90l
