Olfactory groove meningioma presenting solely with visual impairment: illustrative case

The patient's visual acuity and field improved over the following weeks. This case underscores the stealthy and potentially dangerous growth of OGMs, particularly when classical symptoms are absent. It highlights the importance of early imaging in unexplained visual loss and the role of a multidisciplinary approach in managing complex skull base tumors. Greater awareness of atypical presentations may aid in earlier diagnosis and improved outcomes. https://thejns.org/doi/10.3171/CASE25657.
