A rare entity cystic meningioma mimicking as intra-axial brain tumour: Case review

Cystic meningiomas are rare variants of meningiomas; they can pose a radiological as well as histopathological diagnostic dilemma. Leaving behind cystic components at surgery can lead to recurrence of a potentially curable tumour. Cyst will certainly affect the surgical strategy and outcome of these patients, therefore, recognition of this entity and keeping it as a differential is important in making surgical decisions. Here, we discuss 48-year-old female who presented to us with recurrence of left frontotemporal intra-axial tumour according to her previous records as well as new confusing computed tomography and magnetic resonance imaging done after her admission to our institution. The final diagnosis confirmed by intraoperative findings as the tumour was atypical extra-axial dural based cystic meningioma.
