Cystic Meningioma: Case Series and Review of Literature

Abstract

Background: Cystic meningiomas, a rare subtype accounting for only 2–4% of all meningiomas, present significant
diagnostic challenges due to their atypical cystic features. These tumors, which originate from arachnoid cap cells
of the meninges, are typically solid in nature. However, in some cases, cyst formation may occur, potentially as a
result of microcystic degeneration, intratumoral hemorrhage, or necrosis. On neuroimaging, cystic meningiomas
may resemble other cystic intracranial lesions, such as a brain abscesses, cystic astrocytoma, or parasitic cysts,
thus complicating accurate diagnosis and treatment planning. Case Reports: We describe four cases of cystic
meningioma. Case 1 is a 62-year-old female who presented with a sudden attack of seizure. Case 2 is a 50-year-
old female who presented with a 3-month history of progressive left lower limb weakness. Case 3 is a 49-year-old
female who presented with intermittent headaches and blurred vision. Case 4 is a 40-year-old female presented
after an episode of seizure. Conclusion: Cystic meningiomas are rare, benign tumors. Successful treatment with
total surgical removal leads to excellent outcomes, with no recurrence. Effective management requires advanced
imaging, careful surgery, and long-term follow-up
