====== 1897 ====== [[1896]]-[[1898]] [[Heinrich Quincke]] in [[1897]] reported the first cases of [[Idiopathic intracranial hypertension]] (IIH) shortly after he introduced the [[lumbar puncture]] into medicine. It was named [[pseudotumor cerebri]] in [[1904]] but was not well delineated clinically until the 1940's when [[cerebral angiography]] was added to [[pneumoencephalography]] to identify cases of cerebral mass lesions. Foley coined the term [[benign intracranial hypertension]] in [[1955]] but reports from the 1980's demonstrated a high incidence of [[visual loss]] ((Corbett JJ, Savino PJ, Thompson HS, et al. Visual loss in pseudotumor cerebri. Follow-up of 57 patients from five to 41 years and a profile of 14 patients with permanent severe visual loss. Arch Neurol. 1982;39:461–474.)) ((Wall M, Hart WM, Jr., Burde RM. Visual field defects in idiopathic intracranial hypertension (pseudotumor cerebri) Am J Ophthalmol. 1983;96:654–669.)) and the term “benign” is no longer appropriate ---- [[Parsonage-Turner Syndrome]] is named after Maurice Parsonage and John Turner and published in The Lancet in [[1948]] by Parsonage and Turner ((PARSONAGE MJ, TURNER JW. Neuralgic amyotrophy; the shoulder-girdle syndrome. Lancet. 1948 Jun 26;1(6513):973-8. PubMed PMID: 18866299)). The condition, subsequently coined Parsonage-Turner Syndrome, had been previously described in the literature as far back as [[1897]] with many similar clinical presentations of the syndrome reported prior to the extensive study of the syndrome by Parsonage and Turner.
