Introduction: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature.

Case Report: A 36-year-old female patient was reported with anosmia, headache, memory disturbance, and visual impairment and with the diagnosis of olfactory groove meningioma. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to persistence of visual impairment.

Conclusion: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.

Keywords: Olfactory groove meningioma, optic nerve sheath meningioma, anosmia, headache, memory disturbance, visual impairment.
