Spheno-orbital meningioma have traditionally been defined as secondary tumors of the orbit originating from the dura of the sphenoid wing bone. Nevertheless, pathologic findings reveal a distinct periorbital component as a defining feature of these lesions. These tumors are characterized by an intraosseous mass growth leading to a significant hyperostosis involving the sphenoid wing, the orbital roof, the lateral orbital wall and the middle fossa cranial base and to a thin, usually soft-tissue growth at the dura. We report here on the extension of the primary tumor into the orbital cavity and present the surgical approach performed.
传统上，蝶骨-眶脑膜瘤被定义为起源于蝶骨翼骨硬脑膜的眼眶继发性肿瘤。然而，病理检查结果显示，这些病变的一个显著特征是有明显的眶周成分。这些肿瘤的特点是骨内肿块生长，导致蝶骨翼、眶顶、眶外侧壁和中颅窝颅底出现明显的骨质增生，并在硬脑膜处有一层薄的、通常为软组织的生长。我们在此报告原发性肿瘤向眶腔的扩展情况，并介绍所采用的手术方法。
