Coexistence of cervico-thoracic extradural en-plaque meningioma with multiple intracranial meningiomas

Abstract

Meningioma is one of the most common tumors in the spinal cord. Extradural and en-plaque variety of meningioma occur less frequently. A 47-year-old woman is presented with radiculopathy signs. Magnetic resonance imaging revealed a lesion from C6 through T3 vertebral levels compressing the cord both anteriorly and posteriorly. Subtotally excision was performed and histopathologic signs showed transitional type of meningioma (WHO Grade 1). Post operatively, she had good neurological recovery. Intraoperative findings point out that the en-plaque meningioma was pure extradural. Twelve cases of pure extradural en-plaque meningioma have been reported in the literature. Besides, to the best our knowledge coexistence of "en plaque" spinal epidural meningioma with meningiomas in cranial cavity has not been reported. Complete resection is mandatory to prevent recurrence. Moreover, it is considerably difficult to remove the parts of tumor over anterior of the dura without complication.

Purely extradural spinal meningioma: A case report and literature review

“…Resection of spinal extradural meningiomas can be technically difficult and some require a second approach. [ 6 , 7 ] Further, the proximity of spinal extradural meningiomas to vital structures including the cord and vertebral artery may preclude gross total resection, which was achieved in only 43% of the reported cases.…”
