“Sudden” visual loss caused by a transitional meningioma in a young female

Abstract

Intracranial tumors are known to have a broad clinical spectrum. Meningiomas are the second-most common benign tumors, usually affecting women in their sixth or seventh decade of life. The World Health Organization (WHO) classified them into three grades, and Grade 1 meningiomas are considered benign neoplasias. Despite being benign, they are usually located in noble areas of the brain, most frequently in the parasagittal area, followed by the falx, the sinus cavernosus, tuberculum sellae (5%–10%), lamina cribrosa, foramen magnum, and torcular zones, and are important causes of sequelae to the patient. We herein present the case of a young patient who experienced overnight visual loss. Literature shows that several factors are related to visual recovery, which is divided into phases and occurs in approximately 23%–80% of the cases. For the WHO grade 1 tumors, the standard treatment is complete excision of the mass, and it is possible to supplement treatment with stereotactic radiotherapy in atypical, malignant, or recurrent meningioma.
