Study design: Case Report.
Objectives: The aim of this study was to report 2 cases of calcified spinal meningioma that displayed differences in appearance during resection, and to review the current literature on calcified and ossified spinal meningiomas.
Summary of Literature Review: Calcified and ossified spinal meningiomas are rare, and tumor calcification is a risk factor for poor neurological outcomes resulting from the additional manipulations required to dissect the tumor.
Materials and Methods: We describe the clinical course and intraoperative findings of 2 female patients who presented with symptoms of myelopathy. Magnetic resonance imaging showed calcified spinal meningiomas of the thoracic spine. The type of tumor resection performed was dependent on the solidity and texture of the individual tumors.
Results: Pathologic evaluation revealed psammoma bodies, which suggested calcified meningioma. The patients' neurologic symptoms resolved with no neurologic sequelae.
Conclusions: Although there are a few pathologic differences regarding the main type and pathogenesis of ossified and calcified meningioma, both are thought to have a poor prognosis. For these tumors, adequately accounting for the expected poor prognosis and performing a wide laminectomy in order to ensure an adequate surgical margin are important factors for achieving a favorable outcome.
