Vascular, meningeal and parenchymal changes are described and discussed. In the normal situation, tracer protein particles injected into the subarachnoid space perfuse easily through the extracellular spaces but stop at the outer continuous arachnoidal layer. The parenchymal layer, pia-arachnoid, on the other hand, consists of a uni or pluricellular layer which is regularly crossed by tracer particles. Though the internal carotid, vertebral and basilar arteries have some anatomical characteristics in common with peripheral arteries, they have special anatomical characteristics: thinner tunica media and adventitia, the absence of vasa vasorum and the presence of a fluid cushion (CSF) in which they are bathed. The most striking angiographic observation in leptomeningitis is the transmural extravasation of the contrast medium, primarily in arteries within the depths of the cisterns and sulci, producing \u2018halo\u2019 formation. Long after the cerebral circulation time, one may identify contrast media \u2018pooling\u2019 within the cisterns and sulci.<\/jats:p>","DOI":"10.1159\/000119796","type":"journal-article","created":{"date-parts":[[2008,3,5]],"date-time":"2008-03-05T13:10:47Z","timestamp":1204722647000},"page":"1-13","source":"Crossref","is-referenced-by-count":1,"title":["The Physiopathogenetic Basis for the Angiographic Diagnosis of Bacterial Infections of the Brain and Its Coverings in Children"],"prefix":"10.1159","volume":"5","author":[{"given":"Anthony J.","family":"Raimondi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Concezio","family":"Di Rocco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,3,4]]},"container-title":["Pediatric Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/119796","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/119796","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:19:59Z","timestamp":1745461199000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000119796"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1979]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2004,7,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000119796","archive":["Portico"],"relation":{},"ISSN":["1016-2291","1423-0305"],"issn-type":[{"type":"print","value":"1016-2291"},{"type":"electronic","value":"1423-0305"}],"subject":[],"published":{"date-parts":[[1979]]}}}
