Cystic meningiomas: A complex diagnostic challenge and clinicopathological insights from a unique case presentation.

Key Clinical Message: Meningiomas present diverse clinical and radiological characteristics, with cystic formations constituting a lesser subset but posing significant diagnostic hurdles. We explore the complexities of cystic meningiomas through a distinctive case, highlighting the challenges in diagnosis and management due to their variable presentations. A 54‐year‐old female from Bengaluru, Karnataka, initially presented with transient memory disturbances. Brain MRI revealed a sizable left frontal cystic lesion exerting a mass effect and midline shift. However, rapid neurological decline led to an urgent surgical intervention via decompressive craniectomy unveiling unique intraoperative findings and with subsequent histopathological documentation of a Grade WHO 1 cystic meningioma. Cystic meningiomas present intricate diagnostic challenges resembling other intracranial lesions. Various classification systems attempt to categorize these tumors based on their imaging and histopathological characteristics. Despite this, atypical clinical manifestations often lead to misdiagnoses, necessitating a comprehensive approach to differential diagnosis. Further research is crucial to unravel the mechanisms underlying these tumors' cystic changes for improved diagnostic accuracy and tailored therapeutic interventions. [ABSTRACT FROM AUTHOR]
