We report an infant with genetically confirmed\n                    <jats:italic>DEGS1<\/jats:italic>\n                    -related leukodystrophy (homozygous c.337A\u2009&gt;\u2009C, p.Asn113His) who presented with abnormal eye movements and early-onset developmental arrest. This was accompanied by axial hypotonia, severe feeding difficulties, and refractory epilepsy, including epileptic spasms with modified hypsarrhythmia. Brain MRI demonstrated diffuse abnormal myelination per age, thin corpus callosum, and cerebellar involvement. Notably, susceptibility-weighted imaging suggested cerebellar white matter calcifications, which were confirmed on brain CT, alongside punctate supratentorial calcifications, an atypical finding for\n                    <jats:italic>DEGS1<\/jats:italic>\n                    -related disease.

Our findings also underscore the severe clinical course associated with DEGS1 deficiency, including profound developmental impairment, early-onset epilepsy, and persistent feeding difficulties.\n                  <\/jats:p>","DOI":"10.1007\/s10072-026-09147-5","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T02:15:37Z","timestamp":1780971337000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intracranial calcifications in DEGS1-Related Leukodystrophy: a potentially under-recognised neuroimaging feature"],"prefix":"10.1007","volume":"47","author":[{"given":"Ylenia","family":"Vaia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neena","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharmila","family":"Jeyasingh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sniya","family":"Sudhakar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kshitij","family":"Mankad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asthik","family":"Biswas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ata","family":"Siddiqui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Mundy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tammy","family":"Hedderly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9689-8393","authenticated-orcid":false,"given":"Rahul R.","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"issue":"3","key":"9147_CR1","doi-asserted-by":"publisher","first-page":"1240","DOI":"10.1172\/JCI123959","volume":"129","author":"DC Pant","year":"2019","unstructured":"Pant DC, Dorboz I, Schluter A et al (2019) Loss of the sphingolipid desaturase DEGS1 causes hypomyelinating leukodystrophy.
