title: Subdural meningioma of spinal cord. Case report.
abstract: A case of extensive circumferential meningioma of the spinal subdural space is reported. A potential mechanism for this growth pattern is proposed, and preoperative diagnosis by computerized tomography is discussed. This case reinforces the necessity for intradural exploration when an expected extradural neoplasm is not encountered at operation.
