Case Discussion

Meningiomas are the most common extra-axial tumours of the central nervous system. They are a non-glial neoplasm that originates from the arachnoid cap cells of the meninges and are typically benign with a low recurrence rate, but rarely can be malignant.

Meningiomas occur in a magnitude of locations, one of the less common places being the planum sphenoidale. Presentation is often due to symptoms from mass effect or incidental.
