A prognostic model for tumor recurrence and progression after meningioma surgery: preselection for further molecular work-up

A Patient With Giant Meningioma With Intracranial and Extracranial Communication

Atypical meningiomas, classified as World Health Organization (WHO) grade-2 tumors, are characterized by varied and unpredictable clinical behavior. Here, we report the case of an 80-year-old woman with a large meningioma displaying communication both intracranially and extracranially. The histopathological diagnosis confirmed a WHO grade-2 atypical meningioma. After complete surgical resection, the patient experienced a significant improvement in symptoms, with no evidence of recurrence on follow-up imaging. This case highlights the significance of understanding giant intracranial and extracranial communication meningiomas, shedding light on the favorable prognosis associated with WHO grade-2 atypical meningiomas after complete surgical resection.
