Teflon granuloma is an inflammatory giant-cell foreign-body reaction to polytetrafluoroethylene fibers or injection. Tissue augmentation with Teflon has dramatically declined over the past two decades because of its implication in granuloma formation. Nevertheless, Teflon felt is still commonly used in neurosurgical dissection and microvascular decompression. We report a patient with a Teflon granuloma of the skull base discovered 1.5 years after endonasal resection of an olfactory groove meningioma. The case highlights the clinical and radiographic diagnosis as well as the management of this unusual finding.
聚四氟乙烯肉芽肿是对聚四氟乙烯纤维或注射物的一种炎症性巨细胞异物反应。由于其与肉芽肿形成有关,在过去二十年中,使用聚四氟乙烯进行组织填充的情况已大幅减少。尽管如此,聚四氟乙烯毡仍常用于神经外科手术解剖和微血管减压。我们报告了一例患者,在经鼻切除嗅沟脑膜瘤1.5年后发现颅底聚四氟乙烯肉芽肿。该病例突出了这种罕见发现的临床和影像学诊断以及处理方法。
