Spinal meningiomas: evaluation of 41 patients.

AIM: Spinal meningiomas are relatively frequent intraspinal tumors. They constitute 25-46% of all primary spinal neoplasms. METHODS: Forty-one patients with spinal meningiomas surgically treated between 1986 and 2001 are reviewed in this report. There were 32 females and 9 males, aged 16 to 73 years old. Tumor location was cervical in 7 cases and thoracic in 34 cases. All tumors were intradural. All of the patients were operated by laminectomy in prone position. RESULTS: Total excision was achieved in 40 (98%) patients and subtotal excision in 1(2%). The majority of the tumors were meningothelial (42%) or psammomatous (25%). There was no surgical mortality. Four patients (10%) suffered from morbidity: One patient with CSF fistula, 1 deep venous thrombosis, 1 case with paraparesis and 1 wound infection was seen. Neither multiple meningiomas nor malign meningiomas were seen in our series. CONCLUSIONS: Spinal meningiomas are benign tumors and should be excised totally. If the preoperative neurological status is not complicated, fairly good outcome can be achieved.

Tentorial meningiomas.

We report our experience with and long-term results of 37 patients with tentorial meningiomas who underwent surgery between 1972 and 1993. The average age was 43 years, and the mean duration of symptoms was 36 months. Headache (83.8%) and extremity or gait ataxia (35.1%) were the most common complaints. On neurological examination, signs of elevated intracranial pressure and cerebellar deficits (51.4%) were the most common findings, followed by third nerve involvement (35.1%). Computed tomography, angiography, and, in recent years, magnetic resonance imaging were used as diagnostic tools and for planning the surgical procedure. According to the primary site of attachment, the tentorial meningiomas were divided into three subgroups: medial, lateral, and falcotentorial. The lateral and medial tumors, with mainly supratentorial development, were approached from above by using a temporal, temporooccipital, or parietooccipital craniotomy. For tumors developing mainly in the posterior cranial fossa, suboccipital craniectomy was performed. In six patients who showed medial tentorial and petrous apex attachment, a combined subtemporal transpetrosal and retromastoid approach was performed. In 31 patients, the tumors were totally removed, and, in 6 patients, only subtotal excision could be done. Seven patients had postoperative complications, but only one of them died of severe brain edema. Our mortality rate was 2.7%. In this article, appropriate preoperative studies, surgical techniques, and surgical results are discussed.
