“…Spinal meningiomas are most frequently found in the thoracic, followed by the cervical and lumbar spine, and constitute approximately 40% of all benign spinal tumors [Figures 1 – 10 ]. [ 1 2 3 4 5 6 ] Patients may average 50 years of age, but a preponderance is found between the ages of 75 and 84. Symptoms and signs of radiculopathy (root compression) and myelopathy (cord compression) reflect the location of the tumors.…”

“…There are several pathologic types of meningiomas; 70% psammomatous, 15% meningothelial, 7% angiomatous, 7% transitional, and 1% may be cancerous/infiltrative/malignant (e.g., meningiopericytomas, clear cell meningiomas) [Figures 1 – 10 ]. [ 1 2 3 4 5 6 ] They can also demonstrate several growth patterns characterized by initial thickening of the dura, calcification, and dural invasion.…”

“…There are approximately 1,000 spinal meningiomas treated per year in the USA. [ 1 2 3 4 5 6 ] Although they typically occur in the older ages groups of 75–84, some studies reported an average age of just 50. They are much more commonly encountered in females in the thoracic region, followed by the cervical and lumbar spine [Figures 1 – 10 ].…”

“…Most spinal meningiomas are intradural (inside the dura) and extramedullary (outside the spinal cord) [Figures 1 – 10 ]. [ 1 2 3 4 5 6 ] They typically involve an average of 3.2 segments (range 2–5 levels). Most meningiomas (nearly 60%) are located in the thoracic spine, with up to 14-27% found in the cervical region and 7.5–12.7% of cases located in the lumbar spine.…”

“…Spinal meningiomas compromise 40% of all benign spinal tumors; the remainder consist predominantly of neurofibromas/schwannomas [Figures 1 – 10 ]. [ 1 2 3 4 5 6 ] Most are located in the thoracic spine in females vs. males (2.5 to 3.4 times more frequent in females), especially postmenopausal females. Although some reports state these lesions most often occur in patients averaging 50 years of age, others cite more tumors occurring in those 75 to 84 years old.…”

Background:Spinal meningiomas are found in patients typically between the ages of 75 and 84: some report the average age to be 50. They occur with an incidence of approximately 1000 patients per year in the US, are mostly single (90%) rather than multiple (10%), and arise from the spinal meninges (arachnoid/dura). Tumors are typically posterior/posterolateral (70%) in location, leaving the remaining 30% in the anterior/anterolateral spinal canal. They produce symptoms and signs of radiculopathy (nerve root) and/or myelopathy (cord compression) depending on their site of origin.Methods:Meningiomas may be single/sporadic (90%) or multifocal. They may arise primarily/spontaneously, can be radiation-induced, or associated with neurofibromatosis. They are found most frequently in females vs. males in up to a 3.4:1 ratio, occur predominantly in the thoracic spine. They are found in decreasing order in the cervical and lumbar spinal canals. The diagnosis of a meningioma is based on magnetic resonance (MR) studies, where tumors are isointense on T1 weighted MR, and hyperintense onf T2-weighted MR images; they also typically uniformly enhance with Gd-DTPA. On computed tomography (CT) examinations, they are usually characterized as calcified/hyperdense.Results:The neurological deficits resulting from meningiomas and the rapidity of symptom/sign progression dictate whether they are treated surgically or nonsurgically. Management choices include; stereotactic radiation therapy only, and/or in combination with varied surgical resection techniques.Conclusions:The majority of benign spinal cord tumors are meningiomas (40%) that are predominantly found in the thoracic spine in middle-aged females. Tumor levels (e.g. in descending order cervical, thoracic, lumbar), and their location (e.g. anterior/anterolateral 30%; dorsal/dorsolateral 70%) best determine whether nonoperative, operative, and/or operative intervention combined with routine vs. stereotactic radiosurgery are warranted.
