    Abstract

    Multiple extradural arachnoid cysts of the spine are extremely uncommon in children with only a few cases reported. The authors report a case of multiple extradural spinal arachnoid cysts in children with a review of the relevant literature.

    Figures

    Fig. 1
    Preoperative sagittal T1-weighted (A) and T2-weighted (B) spine MR images demonstrating extensive cystic lesion causing spinal cord compression. The spinal cord is pushed ventrally in the spinal canal. Axial T2-weighted MR images obtained at T4 (C) and T11 (D), showing that the cystic lesions are extradural in location.

    Fig. 2
    Intraoperative photographs showing spinal arachnoid cysts. A T10-L2 laminectomy was performed to expose the large extradural spinal arachnoid cyst (A) and thecal sac can be identified to allow dissection of the cyst (B).

    Fig. 4
    Sagittal T2-weighted (A) and Axial T2-weighted (B,C) MR images obtained 2 weeks postoperatively demonstrating expanded spinal cord, complete excision of multiple extradural arachnoid cysts.
