Abstract

Meningiomas of the spinal canal account for approximately 25% of intradural spinal cord tumors in adults. They can arise in any age group but most occur between the fifth and seventh decades of life. Approximately 80% occur in women and approximately 80% are located in the thoracic region. Magnetic resonance imaging is the best diagnostic study; it not only demonstrates the level of the tumor but also its relationship to the spinal cord. Classically, these tumors are located anterolaterally in the intradural space. Most are entirely intradural, but about 10% are both intradural and extradural or entirely extradural. Meningiomas are often covered by a shell-like envelope of spinal cord giving the initial appearance of an intrinsic tumor. Complete surgical removal is the treatment of choice for spinal meningiomas. A meningioma in the upper thoracic area is discussed.
