The Eye That Wandered: A Three-Decade Odyssey, A Case Study

Optic nerve sheath meningiomas (ONSM) are rare, benign intracranial tumors that originate from the meninges surrounding the optic nerve. While ONSM's imaging hallmark is perineural enhancement and calcification, their clinical presentation can be variable, ranging from asymptomatic cases to progressive vision loss. Diagnosing ONSM remains challenging due to the diversity in symptoms, and at times they may mimic other orbital conditions.
