Two cases, both adults, are presented in whom bilateral superior oblique palsy occurred as a result of neoplastic infiltration of the dorsal midbrain in the region of the anterior medullary velum. In the absence of a history of head trauma, the presence of an acquired bilateral superior oblique palsy is a definite sign of a single lesion in the region of the decussation of the trochlear nerves and appropriate imaging is indicated.<\/jats:p>","DOI":"10.1177\/112067219700700312","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T11:10:13Z","timestamp":1523877013000},"page":"271-276","source":"Crossref","is-referenced-by-count":9,"title":["Acquired Bilateral Superior Oblique Palsy: A Localising Sign in the Dorsal Midbrain"],"prefix":"10.1177","volume":"7","author":[{"given":"D.B.","family":"Barr","sequence":"first","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.M.","family":"Mcfadzean","sequence":"additional","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Hadley","sequence":"additional","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Ramsay","sequence":"additional","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.A.","family":"Houston","sequence":"additional","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Russell","sequence":"additional","affiliation":[{"name":"Tennent Institute of Ophthalmology, Glasgow - United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1997,7,1]]},"reference":[{"key":"bibr1-112067219700700312","first-page":"35","volume":"10","author":"Tachibana H.","year":"1990","journal-title":"J Clin Neuro-Ophthalmol"},{"key":"bibr2-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4684-0462-3"},{"key":"bibr3-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1981.03930010078006"},{"key":"bibr4-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9394(14)74718-X"},{"key":"bibr5-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1967.00980020763009"},{"key":"bibr6-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/93.3.567"},{"key":"bibr7-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1970.00990040139003"},{"key":"bibr8-112067219700700312","first-page":"485","volume":"100","author":"Fells P.","year":"1980","journal-title":"Trans Ophthalmol Soc UK"},{"key":"bibr9-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.69.7.508"},{"key":"bibr10-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(12)60201-8"},{"key":"bibr11-112067219700700312","doi-asserted-by":"publisher","DOI":"10.3928\/0191-3913-19861101-03"},{"key":"bibr12-112067219700700312","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1986.01050240045037"},{"key":"bibr13-112067219700700312","first-page":"28","volume":"18","author":"Wise J.","year":"1983","journal-title":"Can J Ophthalmol"},{"key":"bibr14-112067219700700312","first-page":"97","volume":"41","author":"Iwakiri M.","year":"1990","journal-title":"Folia Ophthalmol Jpn"},{"key":"bibr15-112067219700700312","unstructured":"MillerN.R.
