Epidural angiomatous meningioma of the thoracic spine: A case report

Abstract

Abstract. Spinal epidural angiomatous meningiomas (AMs) are extremely rare lesions. Here, we report on a case of an epidural AM of the thoracic spine with chronic but severe cord compression. The patient underwent a T6-T8 laminectomy through the posterior approach. En bloc resection was achieved, and histopathological examination demonstrated an AM. Delayed paraplegia occurred 4 h postoperatively. The patient was treated with methylprednisolone, hyperbaric oxygen and rehabilitation. Gradually, over the next six months, the bilateral leg strength was improved compared with the preoperative status, and no tumor recurrence was noted. Although epidural AM is extremely rare, it should be included in the differential diagnosis of spinal epidural lesions. A definitive diagnosis is difficult based on magnetic resonance imaging alone due to the nonspecific characteristics of the tumor. Since AM is a histologically benign and highly vascularized tumor, timely gross total resection (GTR) is the most effective treatment. A good clinical outcome may be expected following GTR (Simpson grade I and II resection).

Angiomatous Meningioma in the Craniocervical Junction

“…Angiomatous meningiomas are classified as WHO grade 1 meningioma without aggressive nature, while motor and/or sensory deficits and bladder and rectal 2 Case Reports in Orthopedics disturbance can occur as the disease progresses. Spinal angiomatous meningiomas arise most commonly in the thoracic spine followed by the cervical spine [2][3][4][5][6]. The present case is the first report of angiomatous meningioma in the craniocervical junction.…”

“…Spinal angiomatous meningioma is extremely rare. To our knowledge, a total of 16 cases have been reported (Table 1) [2][3][4][5][6]. Angiomatous meningiomas are classified as WHO grade 1 meningioma without aggressive nature, while motor and/or sensory deficits and bladder and rectal 2 Case Reports in Orthopedics disturbance can occur as the disease progresses.…”
