Pedro Rico, 27, Madrid, Tlf.: CT is often the first investigation performed and although not as sensitive as MRI, the nwrvio can often be made, especially if thin slice imaging through the orbits is performed, or coronal and sagittal reconstructions obtained from glioa data. Varying degrees of cystic change and enhancement are demonstrated. Large tumours are typically heterogeneous with cystic and solid components. Histologically the majority are pilocytic astrocytomas.

El papel de la Radioterapia. These tumours have sometimes been divided into optic pathway gliomas and hypothalamic gliomas not to be confused with hypothalamic hamartomas.

In this article we first review the embryological development, anatomy, natural history, and surgical treatment, and then describe the role of radiotherapy RT in the considered entity, indicating how it can be integrated in the pattern of present day care.
