骶部硬膜外囊肿的诊断

目的 探讨骶部硬膜外囊肿诊断中临床表现和CT、MRI、腰椎管造影检查的价值。方法 对13例经手术证实为骶部硬膜外囊肿患者的术前病史、体检及CT、MRI、腰椎管造影检查作回顾性分析。结果 腰腿痛与体位变化有关系，在诊断中具有重要意义，阳性率CT为53．8％，MRI为75％，腰椎管造影为84．6％。结论 在骶部硬膜外囊肿诊断中，应重视腰腿痛与体位变化的关系，强调腰椎管造影时站立延迟透视的重要性。CT、MRI及腰椎管造影检查不能互相替代。

Diagnosis of sacral epidural cyst

Objective To investigate the value of clinical manifestation, CT, MRI and lumbar myelography in the diagnosis of sacral epidural cyst. Methods A retrospective study was performed in 13 cases with sacral epidural cyst confirmed by operation. The clinical manifestation, CT, MRI and lumbar myelography finding were reviewed. Results The lumbocrural pain was sinificantly related to posture. The positive finding rates of CT, MRI and myelography were 53.8%, 75% and 84.6%. Conclusion In the diagnosis of sacral epidural cyst, the relation of lumbarcrural pain with posture should be concerned,and the significance of delayed fluoroscopy in lumbar myelography in standing position should be emphasized. The CT, MRI and lumbar myelography examinations cannot be substituted with each other.
