Abstract

The standard treatment for symptomatic spinal extradural arachnoid cyst (SEAC) is complete surgical removal of cyst and closure of the dural defect. In most cases, total laminectomy has been performed at affected vertebra for complete removal of the SEAC. However, this invasive surgery may result in postoperative kyphosis and back pain. We report a case of large SEAC involving T10-L1 which was excised through the minimal skipped hemilaminectomy, to minimize the risk of postoperative kyphotic deformity. Simultaneously, we closed the dural defect after preoperative precise identification of the site through several radiological studies.
