title: Non-communicating extradural arachnoid cyst of dorsal spine.
abstract: Extradural arachnoid cyst in the spine is an uncommon cause of spinal cord compression in the paediatric population. Most reported cysts have communication with the intrathecal subarachnoid space through a small defect in the dura. The reported child had spinal cord compression caused by a large spinal extradural arachnoid cyst in dorsal spine that did not communicate with the intradural subarachnoid space. Surgical excision of cyst was done with recovery of neurological deficit postoperatively.
