Metastatic follicular thyroid carcinoma to the central nervous system (CNS), including the skull and dura, is exceedingly rare.
The authors present the case of a gigantic, intraosseous, dural-based follicular thyroid carcinoma, highlighting the operative strategy for this mass. They also provide a literature review of CNS metastases of differentiated thyroid carcinoma.
Although follicular thyroid carcinoma rarely metastasizes to the CNS, it should be included in the differential diagnosis of hypervascular intraosseous skull lesions, even in the absence of disseminated metastatic disease. The authors illustrate key operative steps in managing the tumor's hypervascularity, extracranial extension, and posterior sagittal sinus invasion, as well as unintended sequelae from ligating the seemingly occluded anterior and middle third of the superior sagittal sinus in large tumors. https://thejns.org/doi/10.3171/CASE24550.
转移性滤泡状甲状腺癌累及中枢神经系统（CNS），包括颅骨和硬脑膜，极为罕见。
作者报告了一例巨大的、位于骨内、起源于硬脑膜的滤泡状甲状腺癌病例，重点介绍了针对该肿物的手术策略。他们还对分化型甲状腺癌的中枢神经系统转移进行了文献综述。
尽管滤泡状甲状腺癌很少转移至中枢神经系统，但即使在无播散性转移疾病的情况下，它也应纳入高血供骨内颅骨病变的鉴别诊断中。作者阐述了处理肿瘤高血供、颅外扩展及后矢状窦侵犯的关键手术步骤，以及在大型肿瘤中结扎看似闭塞的上矢状窦前三分之二时出现的意外后遗症。https://thejns.org/doi/10.3171/CASE24550
