Since the earliest anatomical descriptions of intra-ventricular tumors, neurosurgeons have shown a high degree of interest in the management of these neoplasms, perhaps because these tumors grow freely in an existing cavity with minimal damage to the underlying brain. As a result, they usually show symptoms related to ventricular enlargement rather than to compression of the adjacent brain. Their surgical removal is facilitated by their particular situation and by the fact that they often present as benign encapsulated tumors.
