Meningioma is one of the commonest spinal tumors, with a predilection for intradural occurrence. Its occurrence as an extradural, en plaque variety with extension into the brachial plexus is unusual.
A 50-year-old male patient presented with progressive spastic quadriparesis. Magnetic resonance imaging showed an en plaque, epidural soft tissue tumor at C5-C7 levels on the right side with extraforaminal extension into the paraspinal region and the brachial plexus laterally. The patient underwent a C5-7 laminectomy and partial excision of the tumor. Histopathology was reported as psammomatous meningioma (World Health Organization grade I).
An extradural spinal meningioma should be considered in the differential diagnosis of an exclusively extradural spinal tumor. Its occurrence as an en plaque variety is uncommon. We report an unusual case of the en plaque form of extradural cervical meningioma with diffuse involvement of the brachial plexus.
脑膜瘤是最常见的脊柱肿瘤之一，好发于硬膜内。其作为硬膜外、斑块状并累及臂丛神经的情况较为罕见。
一名50岁男性患者出现进行性痉挛性四肢瘫。磁共振成像显示右侧C5 - C7水平有一个斑块状硬膜外软组织肿瘤，经椎间孔延伸至椎旁区域并向外累及臂丛神经。患者接受了C5 - 7椎板切除术及肿瘤部分切除术。组织病理学报告为砂粒型脑膜瘤（世界卫生组织I级）。
在仅表现为硬膜外脊柱肿瘤的鉴别诊断中应考虑硬膜外脊膜瘤。其斑块状形式并不常见。我们报告了一例罕见的硬膜外颈椎脑膜瘤斑块状形式并广泛累及臂丛神经的病例。
