- Abstract
Introduction. Spinal extradural meningeal cysts, extradural outpouchings of the arachnoid that communicate with the intraspinal subarachnoid space through a small dural defect, are relatively uncommon. Case Report. We report a case of 35-year-old man with multiple spinal extradural meningeal cysts in the thoracolumbar region. The operative findings revealed a dural defect in one of the cysts that allowed communication between the extradural cyst cavity and the subarachnoid space. Application of the Valsalva maneuver allowed cerebrospinal fluid to flow into the cyst's cavity; however, reverse flow did not occur. Result. These findings indicate that a valve-like mechanism developed in the enlarging cyst, but there was no communication between the extradural cyst cavity and the subarachnoid space in the other cysts. Conclusion. The number of independent cysts makes this case unique and suggests an underlying defect in the dura of the spinal canal in a limited region. Surgical resection of the cyst wall and closure of the dural defect obtained a favorable result.
