Pediatric pineal tumor

The incidence of pineal region tumors in childhood is more than twice as high as in adults. Tumors can cause hydrocephalus and cranial hypertension, compressing adjacent structures, causing the eyes to fail to look up, tinnitus, hearing loss and endocrine disorders, sexual dysfunction, obesity, drowsiness, etc. The age of onset of different tumor types may be slightly different. The peak age of germ cell tumors is 12 to 14 years, the peak of teratoma is 7 to 8 years, and the peak of gliomas in this area is 13 to 15 year old. The majority of men with tumors in the pineal gland area accounted for 79.8%. Children with pineal gland tumors are different from adults in pathological properties. Children are more common in germ cell tumors and teratomas, while adults are more common in gliomas and meningiomas. In this group, 69.4% of the tumors originated from embryonic germ cells, of which 36% were germ cell tumors and 26% were teratomas. Tumors from glial cells accounted for 20%, while tumors from pineal parenchymal cells accounted for 8%.
