Management of primary or recurring grossly cystic craniopharyngiomas by means of draining systems

Summary In primary or relapsing grossly cystic craniopharyngiomas most of the problems related to the neoplastic mass may be, even if temporarily, improved by reducing volume of the cyst. A major surgical approach is unjustified when the aim is only to empty the cyst contents. Drainage of the cyst cavity by means of derivative techniques may be as effective and less invasive; in combined management plans that such tumours often require, they are, therefore, useful complementary procedures that can achieve long-lasting relief of symptoms, provided that the cyst is unilocular.
