CT- MRI Diagnosis Analysis of Cysts in Lumbosacral Canal

目的探讨腰骶管内囊肿的临床表现、CT和MRI诊断及鉴别诊断,以提高对本病的认识。方法回顾性分析19例经手术病理证实的腰骶管内囊肿的影像学特征,并评价CT、MRI对该病的诊断价值,MRI检查19例,CT检查11例。结果在19例腰骶管内囊肿中,肠源性囊肿2例,脊膜囊肿17例;2例多发,其余均为单发;有11例行CT检查,检出囊肿7例;19例全行MRI检查,均查出囊肿。结论MRI是椎管内囊肿的最佳检查方法,MRI可对其作出正确诊断,并指导手术治疗。CT对该病具有一定的诊断价值。

Objective. To study the clinical manifestations, CT and MRI diagnosis and differential diagnosis of cysts in lumbosacral canal, to make a further understanding of the disease.Methods： Imaging features in 19 patients with pathologically proved cyst lumbosacral canal, were retrospectively analyzed. MRI was performed in all 19 cases, of which additional CT scan was carried out in 11 cases. Results： The enteric cysts in 2 cases, spinal meningeal cysts in 17 cases; 2 cases are multiple,17 cases are single, there are 7 cases were discovered by CT scanning in 11 cases,all were discovered by MRI. Conclusion： MRI was the best examining method for diagnosis of spinal meningeal cyst. Thus, MRI was helpful for its diagnosis and management. CT scanning had certain diagnostic value.
