Current recommendations advocate for imaging-based screening of suspected DSTs shortly after birth to exclude associated inclusion lesions. &lt;b&gt;&lt;i&gt;Case Presentation:&lt;\/i&gt;&lt;\/b&gt; A 6-year-old male child presented with a 2-week history of progressive ataxia, lower limb weakness, and hyperreflexia. He was suspected to have a thoracic DST at birth, though initial screening ultrasound was negative for an inclusion lesion or intradural tract. On representation, MRI demonstrated a 3.9-cm intramedullary thoracic dermoid cyst causing significant spinal cord compression. Intraoperatively, a DST extending intradurally was found. The associated dermoid cyst was removed via intracapsular resection. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Whilst dermoid cysts are presumed to progressively develop from DSTs, to our knowledge, this is the first case in English literature documenting a thoracic spinal cord intramedullary dermoid cyst following a negative screening ultrasound for a suspected DST. We use this case to highlight the false-negative rates associated with postnatal screening and advocate for early neurosurgical referral of suspected DSTs, regardless of imaging findings. <\/jats:p>","DOI":"10.1159\/000512580","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T22:02:00Z","timestamp":1611784920000},"page":"79-84","source":"Crossref","is-referenced-by-count":1,"title":["Growth of Intramedullary Spinal Cord Dermoid Cyst from a Congenital Thoracic Dermal Sinus Tract after Negative Screening Ultrasound Imaging"],"prefix":"10.1159","volume":"56","author":[{"given":"Liam G.","family":"Coulthard","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig Robert","family":"Vonhoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmad M.","family":"Badran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas E.","family":"Robertson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin J.","family":"Wood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,1,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-009-0962-z"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159\/000064399"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s10143-005-0382-9"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.3171\/foc.2001.10.1.5"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1053\/j.semperi.2012.11.006"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159\/000439539"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3171\/2015.5.PEDS1537"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.4103\/ajns.AJNS_13_18"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2015.06.038"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.4103\/1817-1745.131478"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-010-1308-6"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/s0031-3955(05)70241-8"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1111\/pde.12485"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-006-0073-z"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-013-2147-z"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/neurosurgery\/30.cn_suppl_1.295"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.3171\/2014.11.PEDS14341"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1542\/peds.112.3.641"}],"container-title":["Pediatric Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/512580","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/512580","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:17:55Z","timestamp":1745425075000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000512580"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021]]},"references-count":18,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2021,3,17]]},"published-print":{"date-parts":[[2021,3,23]]}},"URL":"https:\/\/doi.org\/10.1159\/000512580","archive":["Portico"],"relation":{},"ISSN":["1016-2291","1423-0305"],"issn-type":[{"value":"1016-2291","type":"print"},{"value":"1423-0305","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021]]}}}
