While cGVHD mainly affects the muscles, skin, oral mucosa, eyes, lungs, gastrointestinal tract, and liver, central nervous system (CNS) involvement remains possible and, moreover, is rare when it occurs isolated. CNS-cGVHD can manifest with a wide spectrum of CNS disorders, including cerebrovascular diseases, autoimmune demyelinating diseases, and immune-mediated encephalitis. We present a case of 65-year-old man previously treated with HSCT presenting with progressive cerebrovascular disorder and optic neuropathy without any clear alternative causal processes except for immune-mediated CNS microangiopathy in the context of possible CNS-cGVHD, along with suggestive imaging and instrumental and laboratory findings. Starting one year after HSCT for acute myeloid leukemia, when the first cerebral ischemic event occurred and was then associated with a reduction in visual acuity, an extensive diagnostic work-up had remained inconclusive over many years, leading us to the hypothesis of CNS-cGVHD and, therefore, to the start of immunosuppressive therapy. Our experience highlighted not ignoring the possibility of cGVHD as the underlying mechanism of CNS disorder, even in the absence of other systemic presentations, once more common etiologies of CNS pathological processes have been ruled out.<\/jats:p>","DOI":"10.3390\/ijms26052289","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T13:31:31Z","timestamp":1741095091000},"page":"2289","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Chronic Central Nervous System Graft-Versus-Host Disease to Unravel Progressive Visual Loss and Ischemic Stroke Recurrence Post-Allogeneic Hematopoietic Stem Cell Transplant: A Case Report"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1396-7774","authenticated-orcid":false,"given":"Francesco","family":"Crescenzo","sequence":"first","affiliation":[{"name":"Neurology Unit, Mater Salutis Hospital, AULSS 9 Scaligera, 37045 Legnago, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Danese","sequence":"additional","affiliation":[{"name":"Neurology Unit, Mater Salutis Hospital, AULSS 9 Scaligera, 37045 Legnago, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Dall\u2019Ora","sequence":"additional","affiliation":[{"name":"Neurology B Unit, Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, 37124 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelangelo","family":"Turazzini","sequence":"additional","affiliation":[{"name":"Neurology Unit, Mater Salutis Hospital, AULSS 9 Scaligera, 37045 Legnago, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2852","DOI":"10.1093\/brain\/awq245","article-title":"Neurological manifestations of chronic graft-versus-host disease after allogeneic haematopoietic stem cell transplantation: Report from the Consensus Conference on Clinical Practice in chronic graft-versus-host disease","volume":"133","author":"Grauer","year":"2010","journal-title":"Brain J.
