The authors are reporting on a case of a 55-year-old man with an epidural meningioma in the region from the C VII. to the Th I. segment. The tumor encircled this region, and to the front and right involved the channels through which pass the C VI, C VII. and C VIII. roots. Subdurally, no tumoral mass was found. Another part of this tumor, of the same histological architecture as the epidural cervicospinal part was found in the supraclavicular region to the right, closely connected to the arteries and nerves of this region. The authors discuss the possibility of the tumoral occurrence at this site, primarily taking into account the origin of this tumor from the cells of the outer surface of the arachnoidea, i.e. cap cells which can invade the dura, with later separation from the main arachnoidal layer. The other possibility of such dumbbell meningioma occurring at the outgoing openings of the neural paths from the spinal channel should be looked for in the remnants of the arachnoidal cells in the region of the outgoing openings. In the paper are also discussed and correlated clinico-pathological, CT and angiographic findings.
作者报告了一例55岁男性患者，其颈7至胸1节段区域存在硬膜外脑膜瘤。肿瘤环绕该区域，前部和右侧累及颈6、颈7和颈8神经根穿行的通道。硬膜下未发现肿瘤块。在右侧锁骨上区域发现了该肿瘤的另一部分，其组织学结构与硬膜外颈段脊髓部分相同，与该区域的动脉和神经紧密相连。作者讨论了该部位肿瘤发生的可能性，主要考虑到该肿瘤起源于蛛网膜外表面的细胞，即帽状细胞，其可侵入硬脑膜，随后与主要蛛网膜层分离。这种哑铃状脑膜瘤发生在脊髓通道神经通路出口处的另一种可能性应在出口区域的蛛网膜细胞残余中寻找。本文还讨论了临床病理、CT和血管造影结果并进行了相关性分析。
