Excerpt
Primary intracranial germ cell tumors (GCT) account for 0.4–3.4% [
7] of all pediatric central nervous system tumors in Caucasians and 2.1–9.4% [
4,
6,
13] of all pediatric central nervous system tumors in Asians. Mixed GCTs make up approximately 25% of all intracranial GCTs, and mixed germinomas with matured teratomas make up approximately 4% of all the mixed germ cell tumors [
3]. It has been shown that 76–90% of GCTs are located in the pineal and suprasellar regions [
9]. In addition, this tumor may occur in the basal ganglia, cerebellar vermis, pituitary fossa, ventricular system, optic chiasm, cerebral hemispheres, or in the medulla oblongata [
9]. GCT is known to preferentially occur in the pineal region in males and in the suprasellar region in females [
7]. GCT is usually classified into two types, germinomatous and nongerminomatous germ cell tumors (NGGCT), with the germinomatous type accounting for 50–70% of the GCTs [
