Extradural multiple spinal meningioma. Literature review a case report

A case is reported of recurring or multiple spinal meningioma and focuses again on the incomplete information at present available regarding this class of meningioma. Repeated operations were performed earlier in the extradural space at C2 and an intradural tumour at the same level was completely removed. After a six year interval, we diagnosed an intramedullary meningioma once again at C2, which was subtotally removed. Histological examination indicated an angioblastic tumour, the same type of meningioma as was previously found. Postoperative recovery was satisfactory. Two years later, an intradural extramedullary tumour at T2-3 level was totally removed. Again postoperative recovery went well. In view of the rare occurrence of this meningioma, and the reports on it, we envisaged the pathogenesis of our case as an invasion from the extradural into the intradural space and into the spinal cord. Its appearance in the thoracic region might have been by dissemination via the cerebrospinal fluid pathways or it may have occurred independently.
