====== 1928 ====== see [[1927]] - [[1929]] The [[pineal region]] is a exceptional [[intracranial epidermoid cyst]]. [[Harvey Williams Cushing]] was the first to report the [[pineal]] localization of the epidermoid cyst in [[1928]]. ---- In [[1928]], Cushing and Bailey classified [[cavernous malformation]]s as a solid subtype of [[hemangioblastoma]]s ((Cushing H, Bailey P (1928) Tumors arising from the blood-vessels of the brain. Charles C. Thomas, Springfield)). ---- They distinguished meningothelial, fibroblastic, and angiomatous subtypes, and to this day allocation to subtype is based solely on histological findings. ===== Publications ===== Cushing H, Bailey P (1928) Tumors arising from the blood-vessels of the brain.
