Figure 1: Walter Dandy, a pioneer in intraventricular surgery, demonstrated the techniques of transcallosal and transcortical routes to the lateral ventricle (Dandy WE. The Brain. Hagerstown, MD: WF Prior 1966).

Lateral Ventricular Tumor (Neurocytoma): The Interhemispheric Transcallosal Approach

Mass lesions in the lateral ventricles are rather uncommon and present a particular technical challenge because of their difficult-to-reach location and the neighboring vital diencephalic structures. These tumors are typically benign, grow at a slow rate, and are not identified until they reach a large size.

The tumor types most commonly found within the lateral ventricle are astrocytomas, ependymomas, subependymomas, meningiomas, central neurocytomas, choroid plexus papillomas, and epidermo...
