Papillary meningioma

Papillary meningiomas (PM) are a rare subtype of malignant (WHO grade III) meningiomas that tends to occur in young patients and are characterized by an aggressive growth pattern illustrated by atypical imaging features such as brain and bone invasion. These tumors have a strong tendency of recurrence, and extracranial metastases may also occur.

For a general and broad discussion, please refer to the main article on meningiomas.

Epidemiology

Unlikely typical meningiomas, the papillary subtype presents in children and young patients .

Clinical presentation

Due to their aggressive pattern, these tumors tend to be symptomatic and the clinical presentation will rely on the tumor location. Headaches, seizures, and neurological deficits may occur.

Refer to the main article on meningiomas for a correlation between possible symptoms and tumor locations.
