目的 探讨骶髂关节CT扫描检查骶管囊肿的检出率及漏诊原因.方法 回顾性分析1286例骶髂关节CT扫描患者的骶管改变情况.CT扫描包括骨算法重建及标准算法重建.结果 骶髂关节CT扫描阴性的1 025例患者中发现骶管囊肿36例,检出率为3.5％(36/1 025).其中单发囊肿34例,多发囊肿2例.囊肿位于S1水平5例,S1～2水平4例,S2水平22例,S2～3水平4例,S3水平3例.囊肿最小短径0.5 cm,最大长径3.2 cm,平均1.2 cm.CT表现为类圆形密度均匀的囊性低密度影,伴有骶管扩大19例.CT扫描采用骨算法重建29例,采用标准算法和骨算法重建7例.临床发现并正确诊断11例,仅占30.6％(11/36),约69.4％(25/36)病例出现漏诊.结论 骶髂关节CT扫描阴性患者骶管囊肿检出率约为3.5％,CT扫描宜同时采用标准算法和骨算法重建,以避免漏诊.
目的 探討骶髂關節CT掃描檢查骶管囊腫的檢齣率及漏診原因.方法 迴顧性分析1286例骶髂關節CT掃描患者的骶管改變情況.CT掃描包括骨算法重建及標準算法重建.結果 骶髂關節CT掃描陰性的1 025例患者中髮現骶管囊腫36例,檢齣率為3.5％(36/1 025).其中單髮囊腫34例,多髮囊腫2例.囊腫位于S1水平5例,S1～2水平4例,S2水平22例,S2～3水平4例,S3水平3例.囊腫最小短徑0.5 cm,最大長徑3.2 cm,平均1.2 cm.CT錶現為類圓形密度均勻的囊性低密度影,伴有骶管擴大19例.CT掃描採用骨算法重建29例,採用標準算法和骨算法重建7例.臨床髮現併正確診斷11例,僅佔30.6％(11/36),約69.4％(25/36)病例齣現漏診.結論 骶髂關節CT掃描陰性患者骶管囊腫檢齣率約為3.5％,CT掃描宜同時採用標準算法和骨算法重建,以避免漏診.

Objective To investigate the detection rate and missed diagnosis reason of sacral canal cyst with sacroiliac joint CT scan.Methods Retrospectively analyzed the changes of sacral canal in 1 286 cases with sacroiliac joint CT scan.CT scanning included bone algorithm reconstruction and standard algorithm reconstruction.Results Among 1 025 patients who had negative sacroiliac joint CT scan were found in 36 cases of sacral canal cyst,the detection rate was 3.5％ (36/1 025).Single cyst in 34 cases and multiple cysts in 2 cases.Cyst in S1 level 5 cases,S1-2 level 4 cases,S2 level 22 cases,S2-3 level 4 cases,S3 level 3 cases.The minimal short diameter of the cysts was 0.5 cm and the maximal diameter was 3.2 cm,average 1.2 cm.CT scan showed a round uniform cystic low density,and combined with sacral canal expansion in 19 cases.CT scan used bone algorithm reconstruction in 29 cases,used standard and bone algorithm reconstruction in 7 cases.Clinical findings and correctly diagnosed in 11 cases,accounted for 30.6％ (11/36),about 69.4％ (25/36) cases were missed diagnosis.Conclusions About 3.5％ patients are found sacral canal cyst who have negative sacroiliac joint CT scan.Both the standard and bone algorithm reconstruction should be used to avoid the missed diagnosis of sacral canal cyst.
