“…Infiltration through natural openings, such as the SOF, is a common route for tumor spread from the intracranial space to the orbit 1 . On the other hand, hyperostosis formation occurs when meningiomatous cells invade the Haversian canals, 10 leading to bone overgrowth and extracranial tumor infiltration 9 . In the present case, the association of intraorbital and temporal muscle lesions with spheno‐orbital bone hyperostosis and planum sphenoidal hyperostosis in the sphenoid sinus lesion further emphasizes the importance of identifying these growth patterns in meningiomas.…”
