Pineal region tumors fall into five broad categories: benign pineal region tumors, glial tumors, papillary tumors, pineal parenchymal tumors, and germ cell tumors. Genetic and transcriptional studies have identified key chromosomal alterations in germinomas (RUNDC3A, ASAH1, LPL) and in pineocytomas/pineoblastomas (DROSHA/DICER1, RB1).

===== Pineal parenchymal tumor =====


see [[Pineal parenchymal tumor]]s.
 
===== Germ cell tumors =====

[[pineal germinoma]]: most common (~50% of all tumors)

Pineal [[embryonal carcinoma]]

Pineal [[choriocarcinoma]]

[[Endodermal sinus tumor]]

[[pineal teratoma]]

[[astrocytoma of the pineal gland]]

[[pineal region metastases]]

[[Pineal cyst]]
inclusion cysts (dermoid / epidermoid) 4
meningioma near the pineal region
other rare entities
cavernoma in the pineal region
vein of Galen aneurysm
If invasive, a tectal plate mass may be difficult to distinguish from a pineal mass.
