Cervical Extradural Meningioma: Case Report and Literature Review

Abstract

Background: Extradural lesions are most commonly metastatic neoplasms. Extradural meningioma accounts for 2.7 to 10% of spinal neoplasms and most commonly is found in the thoracic spine. Design: Case report. Findings: A 45-year-old woman presented with posterior cervicothoracic pain for 8 months following a motor vehicle crash. Magnetic resonance imaging of the cervical spine revealed an enhancing epidural mass. Computerized tomography of the chest, abdomen, and pelvis revealed no systemic disease. Due to the lesion's unusual signal characteristics and location, an open surgical biopsy was completed, which revealed a psammomatous meningioma. Surgical decompression of the spinal cord and nerve roots was then performed. The resection was subtotal due to the extension of the tumor around the vertebral artery. Conclusion: Meningiomas should be considered in the differential diagnosis of contrast-enhancing lesions in the cervical spine.

Extradural Spinal Meningioma: Mimicking Metastasis

“…[11] Majority of meningioma are benign therefore after complete excision of tumour prognosis is good but in case of bony involvement and paraspinal extension complete excision of tumor difficult to achieve, and is responsible for the worse prognosis. [12] It is pertinent to be aware of the fact that purely extradural spinal meningioma, especially the "en plaque" variety may mimic metastatic disease (as in our case). [12] Therefore high index of clinical suspicion is warranted.…”

[12] Therefore high index of clinical suspicion is warranted. To conclude, although extremely uncommon, extradural spinal meningioma should be kept as a differential diagnosis for epidural compressive lesions.…”

Intradural Extramedullary Spinal Inflammatory Myofibroblastic Tumor: Case Report and Literature Review

“…Our first diagnosis was that of an epidural tumor based on MRI foraminal enhancement interpreted as lateral extension of the tumor, together with clinical features of an inflammatory tumor, and the fact that en plaque meningiomas of the spine are very rare [21][22][23][24], often occur in middle-aged female patients and are more likely to cause spinal cord compression than radicular symptoms [21]. The pitfall in our management was that as no tumor was found in the epidural space, intradural exploration should have followed.…”

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

“…It is believed that extradural spinal meningiomas are caused by nerve roots, where duramaters are thinner; thus they spread to extradural distance easily. What is assumed for extradural localization is migration of syncytial cells to extradural space or invasion of dura by these cells [6][7][8]. Meningioma usually occurs as the round type, whereas the en-plaque type grows in a sheet-like form along the dura mater.…”
