Abstract
Intradural extramedullary foramen magnum enhancing lesions may be due to meningioma, nerve sheath tumor, aneurysm, or meningeal disease. In this clinical report of 14 patients, we describe a novel imaging finding within the foramen magnum that simulates disease. The lesion is hyperintense on 3D-FLAIR and enhances on 3D gradient-echo sequences but is not seen on 2D-TSE T2WI. It occurs at a characteristic location related to the posterior aspect of the intradural vertebral artery just distal to the dural penetration. Stability of this lesion was demonstrated in those patients who underwent follow-up imaging. Recognition of this apparently benign lesion may prevent unnecessary patient anxiety and repeat imaging.
摘要
硬脊膜内髓外枕骨大孔强化病变可能由脑膜瘤、神经鞘瘤、动脉瘤或脑膜疾病引起。在这份对14例患者的临床报告中，我们描述了枕骨大孔内一种模拟疾病的新型影像学表现。该病变在三维液体衰减反转恢复序列（3D-FLAIR）上呈高信号，在三维梯度回波序列上强化，但在二维快速自旋回波T2加权成像（2D-TSE T2WI）上未见显示。它发生在硬脊膜内椎动脉后方的一个特征性位置，就在硬脊膜穿入处的远侧。在接受随访成像的患者中证实了该病变的稳定性。认识到这种明显良性的病变可避免患者不必要的焦虑和重复成像。
