Intramedullary Tumors

Astrocytomas (Fig. 29.3) are the most common intramedullary tumors. They can occur at any age but are most frequent in the first three decades. The majority of these neoplasms are benign, being either low-grade fibrillary or pilo-cytic astrocytomas. They usually are not well demarcated from the surrounding neural tissue and they may contain cystic areas, as well as adjacent, non-neoplastic cysts.

Gangliogliomas (Fig. 29.4) are benign neoplasms, mostly occurring in children and young
