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.
Case report.
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.
Meningiomas should be considered in the differential diagnosis of contrast-enhancing lesions in the cervical spine.
硬膜外病变最常见的是转移性肿瘤。硬膜外脑膜瘤占脊柱肿瘤的2.7%至10%,最常见于胸椎。
病例报告。
一名45岁女性在机动车碰撞后出现颈胸后部疼痛8个月。颈椎磁共振成像显示硬膜外肿块强化。胸部、腹部和骨盆的计算机断层扫描未发现全身性疾病。由于病变的信号特征和位置不寻常,进行了开放性手术活检,结果显示为砂粒体性脑膜瘤。随后对脊髓和神经根进行了手术减压。由于肿瘤在椎动脉周围延伸,切除为次全切除。
在颈椎强化病变的鉴别诊断中应考虑脑膜瘤。
