Neurosurgical interventions for leptomeningeal tumor

Nonsurgical modalities remain the keystone to treatment and control of leptomeningeal tumor. However, neurosurgical consultation is often required for placement of Ommaya reservoirs and ventriculoperitoneal shunts. In this chapter, the utility of these devices, as well as their common complications will be presented. The aim will be to familiarize non-surgical providers with the indications for and complications associated with these neurosurgical procedures as a component of the adjuvant treatment of leptomeningeal disease.
