    AbstractArachnoid cysts are one of the benign spinal cystic lesions. Multiple nerve roots and spinal cord may be compressed by it, and operating is often recommended. Traditional surgical procedures often choose the posterior median approach, separating the paravertebral muscles, milling the lamina, fully exposing the cyst, partially or completely removing the cyst wall, looking for the leak, and then suturing and sealing. Here we present a case of giant spinal extradural arachnoid cyst in which a ultrafine flexible endoscope was used to visualize cystic spaces and identity the leaks. We repaired the leak after removing part of the cyst wall under the operating microscope, and the patient had an excellent recovery.Copyright © 2022 Elsevier Inc. All rights reserved.
