In opposition to typical cases of its invasive counterpart, that is, chordoma, EP does not show T1-enhancement. Now, we describe three patients with EP, discovered on delayed contrast-enhanced 3D FLAIR performed for endolymphatic hydrops imaging in suspected Meni\u00e8re\u2019s disease. All EP cases demonstrated intense, delayed FLAIR-enhancement of the notochordal remnant. The importance of this new observation of FLAIR-enhancement in EP is threefold: (1) it may increase the detection rate of EP, (2) FLAIR-enhancement in EP should not be mistaken for T1-enhancement in chordoma, and (3) it may open a new window for future imaging studies aiming to better differentiate EP from chordoma.<\/jats:p>","DOI":"10.1177\/19714009241303131","type":"journal-article","created":{"date-parts":[[2024,11,27]],"date-time":"2024-11-27T05:36:39Z","timestamp":1732685799000},"page":"220-223","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Delayed FLAIR-enhancement of benign notochordal remnant (ecchordosis physaliphora)"],"prefix":"10.1177","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4475-6279","authenticated-orcid":false,"given":"Jeroen","family":"Peels","sequence":"first","affiliation":[{"name":"Department of Radiology, AZ Maria Middelares, Ghent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christof","family":"Vulsteke","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Integrated Cancer Center Ghent, AZ Maria Middelares, Belgium"},{"name":"Center for Oncological Research (CORE), Integrated Personalized and Precision Oncology Network (IPPON), University of Antwerp, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Boedts","sequence":"additional","affiliation":[{"name":"Ear, Nose and Throat Department, AZ Maria Middelares, Ghent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eline","family":"Marin","sequence":"additional","affiliation":[{"name":"Ear, Nose and Throat Department, AZ Maria Middelares, Ghent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurens J L","family":"De Cocker","sequence":"additional","affiliation":[{"name":"Department of Radiology, AZ Maria Middelares, Ghent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,11,27]]},"reference":[{"key":"e_1_3_4_2_2","first-page":"1851","article-title":"Retroclival ecchordosis physaliphora MR imaging and review of the literature","volume":"25","author":"Mehnert F","year":"2004","unstructured":"Mehnert F, Beschorner R, K\u00fcker W, et al.
