case_images: Computed tomography revealed a spinal canal widening and remodeling at the level of T11-L1 (Fig. 1A). T11-L1. The cystic lesion had several septations and the cystic fluid showed a signal intensity similar to that of cerebrospinal fluid. (Fig. 1 B-D). T12 and L1. The cystic wall was thin and transparent in the microscopic view (Fig. 1E). Herniated rootlets were identified within the dural defect and the defect was closed with primary suturing without sacrifice or injury of the rootlets (Fig. 1F, G). The six month follow-up plain radiography and MRI showed no recurrence and the patient was satisfied with the outcome and had no neurological complications. (Fig. 1H, I).
