Case Description: We report the case of a 39-year-old woman with a history of renal transplantation on immunosuppressive therapy who presented with recurrent headaches, bilateral visual blurring, visual illusions, and later generalized seizures. Ophthalmological assessment revealed a left homonymous hemianopsia. Brain magnetic resonance imaging (MRI) demonstrated a small (1 cm) right occipital extra-axial lesion suggestive of meningioma. Because of her immunosuppressed status, cerebral lymphoma was also considered, since it has a similar morphology on MRI. A 5-day high-dose corticosteroid trial did not modify the lesion, supporting the diagnosis of meningioma. Conclusion: This case highlights the diagnostic challenges posed by atypical occipital meningiomas and emphasizes that even very small lesions may produce substantial neurological and neuropsychiatric manifestations.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/sni-17-626/figures/SNI-17-626-g001.jpg","publishDate":"2026-10-30T00:00:00.000Z","doi":"10.25259/SNI_1128_2026","categories":["Neuroanatomy and Neurophysiology","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/7b53bfb8-0a99-4079-b85b-0e236a2b7d96/pdf"}
