Extradural neoplasms, especially those arising from the thoracic spinal cord, are rare in children. In our case, the patient is a 3-year-old child with a spinal extradural arachnoid cyst of the spinal cord at the level of VTh6-8. Neuroroentgenological signs indicated a cystic extradural tumor at the level of 6-8 thoracic vertebrae of the spine and spinal cord, which was later confirmed by histopathological findings. The patient was diagnosed with neurological deficits according to the McCormick scale-3 degrees and according to the Frankel scale-C in the preoperative period. An operation was performed-”VTh7 and VTh8 hemilaminectomy, total removal of an extradural cystic tumor. “In the postoperative period, neurological deficits regressed from grade 3 to grade 1 on the Mc-Cormick scale and from type “C” to “E” on the Frankel scale.

Output Extradural cystic neoplasms are benign tumors. Total resection with a positive clinical outcome can be achieved with minimal risk.
