AQP4 are highly expressed on ventricular ependyma. The objective of this study was to describe a novel pattern of linear, \u2018pencil-thin\u2019 enhancement of ventricular ependyma in NMOsd. We report two NMOsd patients with pencil-thin ependymal enhancement along the frontal and occipital horns of lateral ventricles. Differential diagnosis of ependymal enhancement should include NMOsd alongside with infectious and neoplastic etiologies. Pencil-thin ependymal enhancement may be a helpful radiological marker of NMOsd that can be used to differentiate this condition from multiple sclerosis.<\/jats:p>","DOI":"10.1177\/1352458511431730","type":"journal-article","created":{"date-parts":[[2011,12,20]],"date-time":"2011-12-20T00:08:39Z","timestamp":1324339719000},"page":"1050-1053","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":50,"title":["Pencil-thin ependymal enhancement in neuromyelitis optica spectrum disorders"],"prefix":"10.1177","volume":"18","author":[{"given":"Piyush","family":"Banker","sequence":"first","affiliation":[{"name":"Department of Radiology, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Smitha","family":"Sonni","sequence":"additional","affiliation":[{"name":"Department of Radiology, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilya","family":"Kister","sequence":"additional","affiliation":[{"name":"NYU-MS Center, Department of Neurology, New York University School of Medicine, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John P","family":"Loh","sequence":"additional","affiliation":[{"name":"Department of Radiology, New York University School of Medicine, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yvonne W","family":"Lui","sequence":"additional","affiliation":[{"name":"Department of Radiology, New York University School of Medicine, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,12,19]]},"reference":[{"key":"bibr1-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2011.01.002"},{"issue":"3","key":"bibr2-1352458511431730","first-page":"99","volume":"15","author":"Waters P","year":"2008","journal-title":"Int MS J"},{"key":"bibr3-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1016\/j.autrev.2009.04.004"},{"key":"bibr4-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.63.3.390"},{"key":"bibr5-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.2008.01012.x"},{"key":"bibr6-1352458511431730","author":"Downer JJ","year":"2011","journal-title":"Neuroradiology"},{"key":"bibr7-1352458511431730","first-page":"46","volume":"30","author":"Guerini H","year":"2003","journal-title":"J Neuroradiol"},{"key":"bibr8-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.63.7.964"},{"key":"bibr9-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000216139.44259.74"},{"key":"bibr10-1352458511431730","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e3181f8832e"}],"container-title":["Multiple Sclerosis Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1352458511431730","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1352458511431730","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1352458511431730","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T03:33:09Z","timestamp":1777692789000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1352458511431730"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,12,19]]},"references-count":10,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2012,7]]}},"alternative-id":["10.1177\/1352458511431730"],"URL":"https:\/\/doi.org\/10.1177\/1352458511431730","relation":{},"ISSN":["1352-4585","1477-0970"],"issn-type":[{"value":"1352-4585","type":"print"},{"value":"1477-0970","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,12,19]]}}}
