Multiple meningiomas within the spinal canal: case report with 23 tumors

In most series of neoplasms of the spinal canal, spinal cord and its leptomeninges, the incidence of meningioma group comprises approximately 25%. The incidence of multiple meningiomas is small when compared with the frequency of its single occurrence. In the majority of cases, their multiplicity is intracranial and spinal. Multiple meningiomas confined exclusively to the spinal canal are extremely rare. We report on a 33 years-old man, with 23 tumors located in the spinal thoracic region.
