Their significance extends beyond structural support, affecting brain development and function. Methods: This study synthesizes findings from various anatomical, embryological, and neuroimaging research to elucidate the complexities of the leptomeninges. Key methodologies include historical anatomical analysis, contemporary imaging techniques, and examination of pathological states. Results: The review highlights the role of leptomeningeal structures in CSF dynamics, neurovascular interactions, and their involvement in conditions such as hydrocephalus and neurodevelopmental disorders. These insights underscore the leptomeninges\u2019 critical involvement in both normal physiology and disease states. Conclusions: Understanding the intricacies of leptomeningeal anatomy and function is vital for advancing diagnostic and therapeutic approaches in neurodegenerative disorders. This knowledge may facilitate better management strategies in clinical practice, particularly concerning conditions that disrupt CSF flow and brain health.<\/jats:p>","DOI":"10.3390\/neurolint17120203","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T15:15:08Z","timestamp":1765811708000},"page":"203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Leptomeninges: Anatomy, Mechanisms of Disease and Neuroimaging"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7530-818X","authenticated-orcid":false,"given":"Marialuisa","family":"Zedde","sequence":"first","affiliation":[{"name":"Neurology Unit, Stroke Unit, Azienda Unit\u00e0 Sanitaria Locale-IRCCS di Reggio Emilia, Viale Risorgimento 80, 42123 Reggio Emilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0512-9298","authenticated-orcid":false,"given":"Rosario","family":"Pascarella","sequence":"additional","affiliation":[{"name":"Neuroradiology Unit, Ospedale Santa Maria della Misericordia, AULSS 5 Polesana, 45100 Rovigo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"827","DOI":"10.1007\/s00381-012-1744-6","article-title":"The cranial dura mater: A review of its history, embryology, and anatomy","volume":"28","author":"Adeeb","year":"2012","journal-title":"Childs Nerv.
