ABSTRACT
The term ‘meningioma’ was coined by Cushing in 1922 to give a non-specific name to a tumor that was almost always found in proximity to the meninges. Fig. 6.1 illustrates the common location of intracranial meningiomas. Meningeal cells, actually meningothelial arachnoid cap cells, are also found in choroid plexus, tela choroidea, and the arachnoid villi at the spinal nerve exit, explaining why tumors are common in the spinal canal and can also occur intraventricularly and in the pineal region (Table 6.2).
