Abstract
Meningiomas of the spinal axis have been identified from C1 to as distal as the sacrum. Their clinical presentation varies greatly based on their location. Meningiomas situated in the atlanto-axial region may present similarly to some meningiomas of the craniocervical junction, while some of the more distal spinal axis meningiomas are discovered as a result of chronic back pain. Surgical resection remains the mainstay of treatment, although advancements in radiosurgery have led to increased utilization as a primary or adjuvant therapy. Angiography also plays a critical role in surgical planning and may be utilized for preoperative embolization of hypervascular meningiomas.
Highlights
Spinal meningiomas are tumors originating from arachnoid cap cells most commonly situated in the intradural extramedullary region [1,2]
We will discuss the various locations of spinal axis meningiomas, as well as the different surgical approaches, and adjuvant therapies
Because of the well documented success of primarily treating intracranial meningiomas with radiosurgery, it has been thought that radiation would be successful in spinal tumors of similar pathology [51]
Summary
Spinal meningiomas are tumors originating from arachnoid cap cells most commonly situated in the intradural extramedullary region [1,2]. Spinal meningiomas tend to predominate in the thoracic region, they are described in the cervical, lumbar, and rarely the sacral area [3,4,5]. They pose varying surgical challenges based on their regional location, as well as their anterior/posterior orientation to the spinal cord and cauda equina.
