Pathology
Meningioma
Meningiomas are the most common primary intracranial tumour, arising from arachnoid cap cells and attached to the dura, with homogeneous enhancement and a classic dural tail. Most are CNS WHO grade 1 and slow-growing (grades 2 and 3 are atypical and anaplastic), presenting by mass effect specific to their location.
Treatment ranges from observation to resection graded by the Simpson scale for dural involvement, with radiosurgery for small, residual or surgically inaccessible lesions.
