[[Pleomorphic xanthoastrocytoma]] (PXA) was recognized as a distinct entity in [[1979]]
((Kepes JJ, Rubinstein LJ, Eng LF (1979) Pleomorphic xanthoastrocytoma: a distinctive meningocerebral glioma of young subjects with relatively favorable prognosis. A study of 12 cases. Cancer 44:1839–1852))

[[Pseudoprogression]] is primarily reported in patients who underwent [[radiotherapy]] for [[high-grade glioma]], and was first described by Hoffman et al. in [[1979]]. In a study of 51 patients with [[high-grade glioma]], six patients (12 %) had increased computerized tomography (CT) enhancement following radiation, which later disappeared
((Hoffman WF, Levin VA, Wilson CB. Evaluation of malignant glioma patients during the postirradiation period. J Neurosurg. 1979 May;50(5):624-8. doi: 10.3171/jns.1979.50.5.0624. PMID: 430157.))

On 1 October [[1971]] the first patient was scanned and the data sent off for analysis. The resulting images were examined by the hospital's neuroradiologists, neurologists and neurosurgeons who immediately appreciated their value. There was international media interest and hundreds of clinicians visited the hospital to see the new scanner. Hounsfield shared the [[1979]] Nobel Prize in Physiology or Medicine with the physicist Allan M. Cormack "for the development of computer assisted tomography".

The first edition of the [[World Health Organization Classification of Tumors of the Central Nervous System]] was published in [[1979]] and took almost a decade to complete.

The second edition followed in [[1993]] and was considered a great step forward as it incorporated the advances in classification resulting from the introduction of [[immunohistochemistry]].

((Yoshida M, Watanabe M, Kuramoto S. “True” posterior communicating artery aneurysm. Surg Neurol. 1979;11:379–81.))
